Feature/signed public identity (#456)

Browse Source 
* Require signed announces; add Ed25519 key/signature/timestamp TLVs and verify

- Protocol: AnnouncementPacket now requires ed25519PublicKey (0x03), announceSignature (0x04), and announceTimestamp (0x05). Encoder emits, decoder requires; unknown TLVs still tolerated.
- NoiseEncryptionService: add canonical announce sign/verify helpers using context 'bitchat-announce-v1'.
- BLEService: sign Announce, include TLVs; on receive verify (±5 min skew) and ignore unverified; store ed25519 key and isVerifiedNickname in PeerInfo.
- Preserve 8-byte on-wire IDs to keep BLE headers small; no per-message bloat.

* Fix Data.append usage for timestamp bytes in Packets and NoiseEncryptionService (use append(contentsOf:) on UnsafeRawBufferPointer)

* BLEService: fix non-optional announce fields and unwrap signature result; enforce required verification path

* Enforce verified-only public messages; append peerID suffix on nickname collisions in handleMessage

* Suffix duplicate nicknames with peerID prefix in snapshots and getPeerNicknames; ensures lists and messages disambiguate 'jack' vs 'jack'

* Include self nickname in collision detection: suffix remote 'jack' when it matches our nickname in lists and public chat

* UI labels: remove space before '#abcd' suffix in names (public chat, peer lists, snapshots)

* Style '#abcd' suffix light gray:
- Public chat: color suffix in sender via AttributedString segments
- People list: split name and color suffix segment; add helper splitNameSuffix()

* Debounce 'bitchatters nearby' notification: add 60s grace before reset when mesh goes empty; cancel reset when peers return

* Lighten '#abcd' suffix: use Color.secondary.opacity(0.6) in public chat sender and People list

* Toolbar peers indicator: use blue when Bluetooth peers present (was default text color)

* Toolbar peers indicator: use grey when zero peers (was red)

* Toolbar peers indicator: use system grey (Color.secondary) when zero peers, not green

* Fix crash: mutate peripherals dict on BLE queue (not main). Move scan restart to BLE queue as well.

* Reduce connect timeout churn: back off peripherals that time out (15s), increase timeout to 8s, skip non-connectable adverts, and demote timeout log to debug; clean backoff map periodically

* Mentions: support '@name#abcd' disambiguation; filter hashtag/URL styling inside mentions; deliver notifications only to the specified suffixed target when collisions exist

* Fix string interpolation in mention log (escape sequence)

* Mentions: parse '@name#abcd' in sender/receiver; render mention suffix grey (not orange/blue/underlined); ensure receiver notifications trigger for suffixed tokens

* Mentions: include own suffixed token 'name#<myIDprefix>' in valid tokens so '@name#abcd' to self is recognized and notified

* Public actions: show own system message by processing own public messages (remove early-return). Private /hug: add local system message for sender's chat.

* Grammar: change local '/hug' message to past tense ('you hugged/slapped'). Notifications: only fire 'bitchatters nearby' on rising-edge; remove 5-min re-fire and increase empty reset grace to 10m.

* Public /hug echo: add local system message so sender sees action immediately (no reliance on echo)

* Fix visibility: expose addPublicSystemMessage on ChatViewModel and use it from CommandProcessor

* use noise pubkey wip

* ttl=0 for signatures

* verification works
