Extract and use relay hints from bech32 entities (nevent, nprofile, naddr)
and event tag references (e, q tags) to fetch events from hinted relays
not in the user's relay pool.
Changes:
- Parse relay hints from bech32 TLV data in URLHandler
- Pass relay hints through SearchType and NoteReference enums
- Add ensureConnected() to RelayPool for ephemeral relay connections
- Implement ephemeral relay lease management with race condition protection
- Add repostTarget() helper to extract relay hints from repost e tags
- Add QuoteRef struct to preserve relay hints from q tags (NIP-10/NIP-18)
- Support relay hints in replies with author pubkey in e-tags (NIP-10)
- Implement fallback broadcast when hinted relays don't respond
- Add comprehensive test coverage for relay hint functionality
- Add DEBUG logging for relay hint tracing during development
Implementation details:
- Connect to hinted relays as ephemeral, returning early when first connects
- Use total deadline to prevent timeout accumulation across hint attempts
- Decrement lease count before suspension points to ensure atomicity
- Fall back to broadcast if hints don't resolve or respond

This commit brings key local notification logic into the notification
extension target to allow the extension to reuse much of the
functionality surrounding the processing and formatting of
notifications. More specifically, the functions
`process_local_notification` and `create_local_notification` were
brought into the extension target.
This will enable us to reuse much of the pre-existing notification logic
(and avoid having to reimplement all of that)
However, those functions had high dependencies on other parts of the
code, so significant refactorings were needed to make this happen:
- `create_local_notification` and `process_local_notification` had its
function signatures changed to avoid the need to `DamusState` (which
pulls too many other dependecies)
- Other necessary dependencies, such as `Profiles`, `UserSettingsStore`
had to be pulled into the extension target. Subsequently,
sub-dependencies of those items had to be pulled in as well
- In several cases, files were split to avoid pulling too many
dependencies (e.g. Some Model files depended on some functions in View
files, so in those cases I moved those functions into their own
separate file to avoid pulling in view logic into the extension
target)
- Notification processing logic was changed a bit to remove dependency
on `EventCache` in favor of using ndb directly (As instructed in a
TODO comment in EventCache, and because EventCache has too many other
dependencies)
tldr: A LOT of things were moved around, a bit of logic was changed
around local notifications to avoid using `EventCache`, but otherwise
this commit is meant to be a no-op without any new features or
user-facing functional changes.
Testing
-------
Device: iPhone 15 Pro
iOS: 17.0.1
Damus: This commit
Coverage:
1. Ran unit tests to check for regressions (none detected)
2. Launched the app and navigated around and did some interactions to
perform a quick functional smoke test (no regressions found)
3. Sent a few push notifications to check they still work as expected (PASS)

This change includes several source files related to NostrDB into the extension target as well, so that we can use it from that context (and thus enable more advanced push notification formatting and suppression)
To make this change possible, I had to split some source files as well as to move some functions to different files, to ensure we don't have to pull too much unnecessary code into the extension.
Testing
-------
PASS
Device: iPhone 15 Pro simulator
iOS: 17.0.1
Damus: This commit
Test steps:
1. Build DamusNotificationService. Should succeed. PASS
2. Build Damus (the app). PASS
3. Run app, scroll around some notes, go to a few different views, post a note. Should work as normal. PASS
