b8aa0233f9 perf(mobile): verify notification cache events in background (#7650)
On iOS, Buzz stores verified profile and channel information for the
notification extension. The extension uses this cache to show sender and
channel names. Loading profiles or channels also updates the cache.

Cache updates currently check event signatures on the UI thread, even
when the caller does not wait for the update. This can delay taps and
screen updates. This change moves those checks to a background worker.
Signature checks, event selection, community boundaries, and the order
of native writes are preserved.

The worker accepts up to eight batches. When it is busy, later profile
requests stay coalesced before fetching; profiles already loaded remain
available immediately. Overlapping channel updates trigger a fresh
joined-channel cache snapshot after the current export finishes, without
delaying or restarting the channel screen. Queue saturation gets up to
five retries per operation. Pending updates get their own recovery
attempt even if the preceding export fails. Recovery fetches
joined-channel data once and retries cache admission without repeating
relay reads. It does not fetch the open-channel directory. Verified
payloads are split into native-sized writes (256 profiles or 512 paired
channels), keeping the same export ordering. Native profile/channel
write failures retry the same verified chunk while retaining the
export's queue position. All chunks share five retries with 7.75 seconds
total backoff; other native errors fail immediately. Terminal failures
are recorded, and later successful writes do not hide them. Captured
batches keep their original community. Pending channel refetches are
retired on a community switch and refreshed when the user returns. The
cache remains best effort; prolonged failures can still prevent
delivery.

Tests through the production APIs reduced UI delay from 27–31 ms to
below 0.3 ms for four profiles, and from 59–60 ms to below 0.3 ms for
four channel and membership pairs. The native payloads were identical.
This does not measure overall screen speed.

Validation: 2,225 mobile tests passed (one skipped), along with 18
focused export tests, 12 recovery tests, 39 native Swift tests, 35
focused profile tests, and static analysis. Production regressions cover
13-entity bursts, invalid newer events, community rebuilds, reentrant
refreshes, and terminal failures. Regression tests fail when producer
recovery controls, terminal-failure draining, or member-only recovery
scope are removed.

41c5ace937 perf(mobile): move profile sig checks off main thread (#7648)
The mobile app loads user profiles to show names, avatars, and agent
ownership. Some profiles include a signature that proves who owns the
agent. Checking these signatures for a batch of profiles can block
interaction because the checks run on the same thread that draws the
screen and handles input.

This change moves profile batch parsing and signature checks to a
background worker. It processes one batch at a time and combines queued
profile requests. It keeps the same signature checks, preserves newer
profiles that arrive while a batch runs, and discards results after a
community change. Individual live profile updates still use synchronous
verification.

Tests cover newer live updates, community changes, overlapping requests,
stale malformed events, and UI timer responsiveness through the
production parser. The responsiveness test fails if parsing is moved
back to the UI isolate. A regression also exercises a confirmed profile
save while an older batch is paused, including preservation of verified
ownership. All 38 focused tests, all 2,132 mobile tests, and the
analyzer pass.

With 500 valid owner signatures, an AOT test reduced the main-isolate
timer delay from about 3.4 seconds to less than a millisecond. Total
verification time stayed similar. This measures verification work, not
overall screen speed.

GitHub CI passes. The full local test run failed on two timing-sensitive
ACP tests in unchanged Rust code; both passed isolated retries. All
other local checks passed, including the downstream tests and builds run
after that failure.

c432a111ca feat(mobile): push notifications MVP (#6269)
This PR implements MVP, iOS-only,
[NIP-PL](8d2d0ff5ad/docs/nips/NIP-PL.md)-compliant
push notifications.

A relay with `BUZZ_PUSH_ENABLED` will send a push notification for any
message that appears in the in-app Notifications tab.

## Enrollment flow
The first time the client first connects to a relay with
`BUZZ_PUSH_ENABLED`:

    NSE->>iOS: Complete notification: title, body, subtitle<br/>thread ID, exact-message target
```

relay → push gateway → APNs -> NSE -> Notification Center

## Known limitations

The APNs wake payload is intentionally constant and opaque: it contains
no originating community or message identifier, in keeping with the
implemented NIP-PL privacy design.

The Notification Service Extension must therefore reconnect to the relay
and resolve eligible messages after each wake. Around overlapping wakes,
timing boundaries, or resolution windows, notification presentation may
occasionally omit an expected message or display a message more than
once.

This best-effort behavior is deliberately accepted for the current
implementation and will be measured during the internal rollout to
determine whether the user experience is acceptable before any broader
deployment; the implementation does not claim exactly-once presentation.

## Validation

Live end-to-end hardware validation used an internal remotely hosted
development relay and push gateway, the APNs sandbox, and a physical
iPhone 12 mini:

- A second real Buzz client published a uniquely marked message through
the hosted relay.
- The relay matched the message and sent the constant opaque wake
through the hosted gateway. The gateway made an actual APNs request; no
`simctl push` or simulated notification was used.
- The iPhone received the notification on its lock screen. The
Notification Service Extension reconnected to the relay, fetched the
event, verified its ID and signature, and replaced the placeholder
content with the real notification title and body.
- After the app populated its shared presentation cache, a final marked
notification visibly showed the sender display name, sender avatar, and
hashtag-prefixed channel name.
- Tapping a lock-screen notification opened Buzz and exercised the
notification-response path and navigated to the corresponding message.

Final validation with a dogfood-signed artifact and production App
Attest/APNs configuration remains a release step.
