This commit adds more safeguards to prevent RUNNINGBOARD 0xdead10cc
crashes, by:
1. Using the `beginBackgroundTask(withName:expirationHandler:)` to
request additional background execution time before completely
suspending the app. See https://developer.apple.com/documentation/xcode/sigkill
2. Reorganizing app closing/cleanup tasks to be done in parallel when
possible to decrease time needed to cleanup resources.

This should prevent RUNNINGBOARD 0xdead10cc crashes related to
ProfileManager and app background states.

This should prevent background crashes caused by race conditions between
usages of Ndb and the Ndb/app lifecycle operations.

Through some local experimentation, it seems that network relays can support higher subscription limits.
Increase internal limits to avoid hitting issues with subscriptions
waiting on subscription pool to clear and appearing stale.

This reduces the overall subscription usage throughout the app, thus
reducing issues associated with too many subscriptions being used at
once, and the resulting staleness.

This commit improves the loading speed for the home timeline (and likely
other areas of the app) by employing various techniques and changes:
- Network EOSE timeout reduced from 10 seconds down to 5 seconds
- Network EOSE does not wait on relays with broken connections
- Offload HomeModel handler event processing to separate tasks to
avoid a large backlog
- Give SubscriptionManager streamers more fine-grained EOSE signals for
local optimization
- Only wait for Ndb EOSE on the home timeline for faster loading
- Add logging with time elapsed measurements for easier identification of
loading problems

This commit takes a step back from the full local relay model by
treating NostrDB as one of the many relays streamed from, instead of the
one exclusive relay that other classes rely on.
This was done to reduce regression risk from the local relay model
migration, without discarding the migration work already done.
The full "local relay model" behavior (exclusive NDB streaming) was
hidden behind a feature flag for easy migration later on.

Rogue relays could in theory attack nostrdb by replaying ids and
signatures from other notes. This fixes this weakness by calculating the
id again in ndb_note_verify.
There is no known relays exploiting this, but lets get ahead of it
before we switch to the outbox model in damus iOS/notedeck

This adds some helpers for adding custom filtering logic
to nostr filters. These are just a callback and a closure.
There can only be one custom callback filter per filter.

The basic idea of this is to allow you to use the standard
nip50 query interface to search for profiles using our profile
index.
query: {"search":"jb55", "kinds":[0]}
will result in a profile_search query plan that searches kind0 profiles
for the corresponding `name` or `display_name`.

Add support for relay-based filtering in nostr queries.
Filters can now include a "relays" field. Optimal performance when
you include a kind as well:
{"relays":["wss://pyramid.fiatjaf.com/"], "kinds":[1]}
This corresponds to a `ndb` query like so:
$ ndb query -r wss://pyramid.fiatjaf.com/ -k 1 -l 1
using filter '{"relays":["wss://pyramid.fiatjaf.com/"],"kinds":[1],"limit":1}'
1 results in 0.094929 ms

Add relay indexing for existing notes
This patch introduces a relay index for new notes and notes that have
already been stored, allowing the database to track additional relay
sources for a given note.
Changes:
- Added `NDB_WRITER_NOTE_RELAY` to handle relay indexing separately from
new note ingestion.
- Implemented `ndb_write_note_relay()` and
`ndb_write_note_relay_kind_index()` to store relay URLs.
- Modified `ndb_ingester_process_event()` to check for existing notes
and append relay info if necessary.
- Introduced `ndb_note_has_relay()` to prevent duplicate relay entries.
- Updated LMDB schema with `NDB_DB_NOTE_RELAYS` (note_id -> relay) and
`NDB_DB_NOTE_RELAY_KIND` (relay + kind + created_at -> note).
- Refactored `ndb_process_event()` to use `ndb_ingest_meta` for tracking
relay sources.
- Ensured proper memory management for relay strings in writer thread.
With this change, nostrdb can better track where notes are seen across
different relays, improving query capabilities for relay-based data
retrieval.

This commit improves NostrNetworkManager interfaces to be easier to use,
and with more options on how to read data from the Nostr network
This reduces the amount of duplicate logic in handling streams, and also
prevents possible common mistakes when using the standard subscribe method.
This fixes an issue with the mute list manager (which prompted for this
interface improvement, as the root cause is similar to other similar
issues).
