Closes the last cleartext private-content path over BLE: private DM images/voice were sent as plaintext signed fileTransfer packets, TTL-relayed across the mesh, so every relay saw the full bytes. Now the complete BitchatFilePacket is encrypted as a single Noise AEAD message (inner type 0x20, matching Android) and the opaque ciphertext is fragmented. Adds an authenticated in-session capability proof (0x21 TLV: capabilities + Ed25519 key), TOFU-style downgrade pinning, a per-send consent dialog for the signed-cleartext fallback to legacy peers, and a cancellation/admission registry so cancel/delete cannot race a deferred cleartext send.
Android wire constants (0x20 / 0x21 / capability bit 8) confirmed shipping. The 256-fragment preflight cap applies only to the directed fileTransfer migration fallback; encrypted media to capable peers uses the full receiver ceiling.
Rebased over #1428/#1349: identity reads go through BLELocalIdentityStateStore; the session-bound authenticated signing-key check and the announce-path TOFU pin are kept as complementary checks. Full local suite green (1744+197 tests).
TOFU-pins the Ed25519 signing key per noise key so a self-consistent announce that reuses a victim's peerID+noise key with the attacker's signing key/nickname is rejected instead of overwriting the registry and persisted identity. Complements #1432: that PR's signed-LEAVE verification reads the stored signing key this PR protects from announce-path poisoning.
Rebased onto main as a single commit; swift build --build-tests green, 40/40 targeted tests incl. the spoofing e2e cases, and #1432's suites 50/50 unaffected.
* Isolate tests from the developer's real login keychain
Every test run prompted for the login keychain password (repeatedly,
since the xctest runner's code signature changes each build, so
"Always Allow" can never stick) and silently deleted the developer's
real Nostr identity via panic-mode tests.
Two holes let tests reach the real keychain:
- NostrIdentityBridge() defaulted to the real KeychainManager. Tests
inject mocks, but app-side constructions with no injection point
(LocationNotesManager's static bridge, GeohashPresenceService,
BoardManager, AppRuntime) read the real chat.bitchat.nostr item
when exercised under test.
- clearAllAssociations() used raw SecItem* calls that bypassed the
injected keychain entirely, so panicClearAllData tests wiped the
real Nostr identity items on every run.
Fix: centralize FavoritesPersistenceService's test-guarded in-memory
default as KeychainManager.makeDefault() and use it for all default
keychain parameters, and add deleteAll(service:) to
KeychainManagerProtocol so clearAllAssociations() goes through the
injected keychain like every other operation.

* Share one in-memory test keychain per process (Codex P2)
A fresh store per makeDefault() call diverges from production, where
separate default-constructed bridges share chat.bitchat.nostr —
BoardManager's publish and NIP-09 delete paths would derive different
geohash identities under test. PreviewKeychainManager gains a lock
since the shared instance is reached from arbitrary threads.
