Adds comprehensive tests to prevent regression of issue #3165 where
repost notifications were incorrectly blocked by home feed deduplication.
Tests cover:
- Regression test: notifications not blocked by home dedup (main fix)
- Home feed deduplication still works correctly
- Dedup tracks inner event ID, not repost event ID
- Context isolation (.other context doesn't affect dedup)
Each test documents the expected behavior and provides clear failure
messages to aid debugging if the bug reoccurs.

The repost deduplication logic was incorrectly placed before the context
switch in handle_text_event(), causing notification events to be filtered
out when the same note had already been reposted in the home feed.
This fix moves the dedup logic inside the .home case where it belongs.
Notifications should always show reposts of YOUR posts, even if the same
note was already reposted by someone else in your home feed.
Root cause: commit bed4e00 added home feed dedup but placed the logic
before the context switch, affecting all contexts instead of just home.
Note on nostrdb: This bug is purely in application routing logic and
does not require database-level changes. The existing nostrdb TODO
(about inner event validation) is unrelated to this notification issue.

This commit fixes the background crashes with termination code
0xdead10cc.
Those crashes were caused by the fact that NostrDB was being stored on
the shared app container (Because our app extensions need NostrDB
data), and iOS kills any process that holds a file lock after the
process is backgrounded.
Other developers in the field have run into similar problems in the past
(with shared SQLite databases or shared SwiftData), and they generally
recommend not to place those database in shared containers at all,
mentioning that 0xdead10cc crashes are almost inevitable otherwise:
- https://ryanashcraft.com/sqlite-databases-in-app-group-containers/
- https://inessential.com/2020/02/13/how_we_fixed_the_dreaded_0xdead10cc_cras.html
Since iOS aggressively backgrounds and terminates processes with tight
timing constraints that are mostly outside our control (despite using
Apple's recommended mechanisms, such as requesting more time to perform
closing operations), this fix aims to address the issue by a different
storage architecture.
Instead of keeping NostrDB data on the shared app container and handling
the closure/opening of the database with the app lifecycle signals, keep
the main NostrDB database file in the app's private container, and instead
take periodic read-only snapshots of NostrDB in the shared container, so as
to allow extensions to have recent NostrDB data without all the
complexities of keeping the main file in the shared container.
This does have the tradeoff that more storage will be used by NostrDB
due to file duplication, but that can be mitigated via other techniques
if necessary.

This adds a sync mechanism in Ndb.swift to coordinate certain usage of
nostrdb.c calls and the need to close nostrdb due to app lifecycle
requirements. Furthermore, it fixes the order of operations when
re-opening NostrDB, to avoid race conditions where a query uses an older
Ndb generation.
This sync mechanism allows multiple queries to happen simultaneously
(from the Swift-side), while preventing ndb from simultaneously closing
during such usages. It also does that while keeping the Ndb interface
sync and nonisolated, which keeps the API easy to use from
Swift/SwiftUI and allows for parallel operations to occur.
If Swift Actors were to be used (e.g. creating an NdbActor), the Ndb.swift
interface would change in such a way that it would propagate the need for
several changes throughout the codebase, including loading logic in
some ViewModels. Furthermore, it would likely decrease performance by
forcing Ndb.swift operations to run sequentially when they could run in
parallel.

When a view subscribes to profile updates via streamProfile() or
streamProfiles(), the stream now immediately yields any existing
profile data from NostrDB before waiting for network updates.
Previously, subscribers had to wait up to ~1 second for the
subscriptionSwitcherTask to restart the profile listener before
receiving any data. During this window, views would display
abbreviated pubkeys (e.g., "npub1abc...") or robohash placeholders
instead of the cached profile name and picture.
The fix adds a simple NDB lookup when creating the stream. This has
negligible performance impact since:
- It's a one-time operation per subscription (not per update)
- The same lookup was already happening in view bodies anyway
- NDB lookups are fast local queries
A new `yieldCached` parameter (default: true) allows callers to opt
out of the initial cached emission. NoteContentView uses this to
avoid redundant artifact re-renders — it only needs network updates
since its initial render already uses cached profile data.
Furthermore, when a profile has no metadata, the display name now shows
"npub1yrse...q9ye" instead of "1yrsedhw:8q0pq9ye" for a better UX.

During profiling, I found that some large hangs were being caused by a
large number of `notify` calls (and their handling functions) keeping
the main thread overly busy.
We cannot move the `notify` mechanism to a background thread (It has to
be done on the main actor or else runtime warnings/errors appear), so
instead this commit removes a very large source of notify calls/handling around
NoteContentView, and replaces it with a background task that streams
for profile updates and only updates its view when a relevant profile is
updated.

Modified AutoSaveViewModel.needsSaving() to not reset the timer if already
counting down. This ensures the timer starts when the user begins typing and
continues counting even if they keep typing continuously, leading to auto-save
every few seconds instead of waiting for the user to stop typing.
Added automated tests for the new behavior.
Fixes the issue where drafts would only save after user stops typing,
potentially leading to data loss if the app is closed too quickly.

The notifications stream used streamIndefinitely(), discarding EOSE signals. This caused a race condition where:
1. NotificationsView.onAppear fires and calls flush().
2. flush() finds an empty queue (events haven’t arrived yet).
3. Events arrive and queue up in incoming_events.
4. No second flush happens, so notifications stay blank.
Fix: Switch to advancedStream() and handle .ndbEose to flush queued notifications once the local database finishes loading. This mirrors how the Home timeline handles initial data loading.
The ndbEose handler also disables queuing (set_should_queue(false)), so any events arriving after the initial load display immediately.
When the Notifications tab becomes visible, disable queuing so any events arriving afterward insert immediately into the displayed list.
This defensive measure complements the ndbEose flush in HomeModel. Together, they provide belt-and-suspenders protection:
1. ndbEose flush (primary): Triggers when local DB finishes loading, flushing queued events and disabling queuing.
2. onAppear disable (safety net): If the user navigates to notifications before ndbEose fires, this ensures new events aren’t queued forever.
Whichever fires first wins - both set should_queue=false, and the second call is a harmless no-op.

This commit redesigns the Ndb.swift interface with a focus on build-time
safety against crashes.
It removes the external usage of NdbTxn and SafeNdbTxn, restricting it
to be used only in NostrDB internal code.
This prevents dangerous and crash prone usages throughout the app, such
as holding transactions in a variable in an async function (which can
cause thread-based reference counting to incorrectly deinit inherited
transactions in use by separate callers), as well as holding unsafe
unowned values longer than the lifetime of their corresponding
transactions.

We have mechanisms in place to close NostrDB streams when the database needs to
close; however, there is a short time window where those streams are
closing down but the database still has its "open" property set to `true`,
which means that new NostrDB streams may open. If that happens, those
new streams will still be active when NostrDB gets closed down,
potentially causing memory crashes.
This was found by inspecting several crash logs and noticing that:
- most of the `ndb.close` calls are coming from the general
backgrounding task (not the last resort backgrounding task),
where all old tasks are guaranteed to have closed (we wait for all of
them to close before proceeding to closing NostrDB).
- the stack traces of the crashed threads show that, in most cases, the
stream crashes while they are in the query stage (which means that
those must have been very recently opened).
The issue was mitigated by signalling that NostrDB has closed (without
actually closing it) before cancelling any streaming tasks and officially
closing NostrDB. This way, new NostrDB streaming tasks will notice that
the database is closed and will wait for it to reopen.
No changelog entry is needed as this issue was introduced after our last public
release.

Since 991a4a8, the `make_actionbar_model` function introduced an async
call to populate the action bar data.
This surfaced a pre-existing problem where the action bar model would
reinstantiate in any SwiftUI render pass for the chat bubbles in
`ChatroomThreadView`. This issue was not visible before because the whole
computation happened directly on the main actor during the render,
maintaining the illusion of a stable entity. Since the computation was
moved to an async task (for performance and concurrency design reasons),
it caused the action bar items to reload in each render pass, causing
multiple re-renders and the jumpiness witnessed in the ticket.
The issue was addressed by making the action bar model initialization
happen within ChatEventView itself, and wrapping it on `StateObject` to
make that entity stable across re-renders.
This fixes an issue for an unreleased change, so no changelog entry is
necessary.

This fixes a crash that would occasionally occur when visiting profiles.
NdbTxn objects were being deinitialized on different threads from their
initialization, causing incorrect reference count decrements in thread-local
transaction dictionaries. This led to premature destruction of shared ndb_txn
C objects still in use by other tasks, resulting in use-after-free crashes.
The root cause is that Swift does not guarantee tasks resume on the same
thread after await suspension points, while NdbTxn's init/deinit rely on
thread-local storage to track inherited transaction reference counts.
This means that `NdbTxn` objects cannot be used in async functions, as
that may cause the garbage collector to deinitialize `NdbTxn` at the end
of such function, which may be running on a different thread at that
point, causing the issue explained above.
The fix in this case is to eliminate the `async` version of the
`NdbNoteLender.borrow` method, and update usages to utilize other
available methods.
Note: This is a rewrite of the fix in https://github.com/damus-io/damus/pull/3329

Previously, the note content rendering logic would wait for the note
and its blocks to be available in NostrDB before displaying the parsed
version of the note to the user.
However, it is now possible to parse those on demand, and there are code
paths to ensure that it will do so if those parsed blocks are not
readily available from NostrDB.
Therefore, the wait is not necessary, and removing it fixes the delay we

A race condition was identified where notes would get dropped if they
get indexed in the time window between when a query is made and the subscription is made.
The issue was fixed by making the subscribe call before making the query
call, to ensure we get all notes from that time when we perform the
query.
This dropped the failure rate for ndb subscription tests from about 20%
down to about 4%.

This attempts to reduce race conditions coming from Ndb streaming
functions that could lead to lost notes or crashes.
It does so by making two improvements:
1. Instead of callbacks, now the callback handler uses async streams,
which reduces the chances of a callback being called before the last
item was processed by the consumer.
2. The callback handler will now queue up received notes if there are
no listeners yet. This is helpful because we need to issue the
subscribe call to nostrdb before getting the subscription id and
setting up a listener, but in between that time nostrdb may still
send notes which would effectively get dropped without this queuing
mechanism.
