perf(chat): batching, spam rate-limits, near-dup LRU, adaptive flush, faster trims, regex/detector reuse, conditional animations, late-insert, current-mode prewarm, Swift 6-safe timer/closures

* Remove link previews: link URLs inline\n\n- Delete LinkPreviewView and all references\n- Strip preview usage from ContentView\n- Make detected URLs tappable via .link attribute\n- Add MessageTextHelpers for tokens/length checks\n- Wire helpers into iOS/macOS targets

* Peer list UX: match message colors, use map pin icon, stable ordering\n\n- Color list names and icons with same peer color as messages\n- Default icon mappin; teleported uses face.dashed (iOS)\n- Geohash: move teleported peers to bottom\n- Maintain stable order: append new peers, remove missing\n- Mesh list: replace state icons with colored mappin/person

* Fix peer list build errors: remove ambiguous Set type, avoid guard in ViewBuilder, remove duplicate bindings, and simplify person lookup

* Peer list: remove onChange expressions to avoid type-check issues; rely on ObservedObject updates

* Peer lists: simplify view structure to satisfy SwiftUI type checker (replace Group with VStack, flatten body)

* Peer lists: move ordering mutations to onAppear/onChange, keep body pure; fix result builder errors

* Fix: remove trailing modifiers outside if/else to avoid ViewBuilder type issues

* Color parity: fix seed cache to include color scheme; normalize Nostr seeds; switch to mappin.circle icon

* Peer colors: ensure exact match with message colors\n\n- Mesh list uses same seed logic as messages (getNoiseKeyForShortID fallback)\n- Color cache keyed by theme; normalize nostr seeds\n- Icons: use mappin.and.ellipse (default) and face.dashed for teleported\n- Teleport tag: accept "teleported" in addition to "teleport" and presence events

* Fix geohash color mismatch: populate nostrKeyMapping before building messages in resubscribe; also honor t,teleport tag for teleported state

* Message actions: username tap opens sheet via clickable AttributedString; message tap inserts @mention; rename to 'direct message'

* Cashu UX: suppress 'Show more' when message contains a Cashu token (chips handle rendering)

* Cashu detection: broaden regex (allow '.') + shorter min length; avoid long-text fallback when Cashu present so chips render and no full blob

* Geohash levels: rename region->province, country->region; update labels, precision, UI, manager mapping, tests; add Codable backward-compat for renamed cases

* Fix braces in LocationChannel.swift: close enum before extension to satisfy file-scope declarations

* Geohash links: make #geohash tappable and open that channel (bitchat://geohash/<gh>); handle in ContentView.onOpenURL with validation and selection

* Underline tappable #geohash mentions for clarity

* Geochat: sanitize timeline on channel switch to remove any blank-content entries (prevents blank rows)

* Xcode project: sync sources after UI changes (remove LinkPreview, add helpers, update build refs)

 ### 4.2. Favorites and Blocking
 
 To improve the user experience and provide control over interactions, the protocol supports:
-*   **Favorites:** Users can mark trusted or frequently contacted peers as "favorites." This is a local designation that can be used by the application to prioritize notifications or display peers more prominently.
+*   **Favorites:** Users can mark trusted or frequently contacted peers as "favorites". This is a local designation that can be used by the application to prioritize notifications or display peers more prominently.
 *   **Blocking:** Users can block peers. When a peer is blocked, the application will discard any incoming packets from that peer's fingerprint at the earliest possible stage, effectively silencing them without notifying the blocked peer.
