Add censorship-resistant NIP-05 verification using the Namecoin blockchain.
Users can set their nip05 field to a .bit domain (e.g. alice@example.bit)
or direct Namecoin name (d/example, id/alice) and Amethyst will resolve
the pubkey mapping via ElectrumX instead of HTTP.
Resolution uses the standard Electrum protocol (scripthash-based lookups):
- Build canonical name index script matching ElectrumX-NMC indexing
- Query blockchain.scripthash.get_history for the name's tx history
- Parse NAME_UPDATE script from the latest transaction output
- Extract Nostr pubkey from the name's JSON value
Supports both d/ (domain) and id/ (identity) Namecoin namespaces,
simple and extended NIP-05-like value formats with relay hints,
LRU caching with 1h TTL, and self-signed TLS certificates.
New files:
- quartz: ElectrumxClient, NamecoinNameResolver, NamecoinLookupCache
- amethyst: NamecoinNameService, Nip05NamecoinAdapter, NamecoinVerificationDisplay
- docs: namecoin-nip05-design.md
- tests: NamecoinNameResolverTest
Modified:
- Nip05Client: optional namecoinResolver routes .bit to blockchain
- AppModules: wire up resolver
See docs/namecoin-nip05-design.md for full architecture and protocol details.
Covers the full expect/actual contract across all platforms (Android,
JVM, iOS):
- round-trip for empty, single-char, simple, unicode, and JSON strings
- repetitive input compresses to a smaller size
- gzip magic number (0x1F 0x8B) present in compressed output
- compressed bytes differ from raw input bytes
- decompress of invalid data throws an exception
- special/control characters survive a round-trip

Uses platform.zlib (built-in on all Apple targets) via Kotlin/Native
cinterop to provide the actual GZip implementation:
- compress: deflateInit2 with windowBits=31 (MAX_WBITS+16) for gzip
format; deflateBound gives a tight upper-bound so a single Z_FINISH
call is always enough – no output loop required.
- decompress: inflateInit2 with windowBits=47 (MAX_WBITS+32) for
automatic gzip/zlib format detection; output is collected in
fixed-size chunks to handle arbitrary decompressed sizes.

- Add focused game mode to ChessPollingDelegate: when viewing a game,
only that game is polled instead of all active games
- Fix pawn promotion by parsing promotion suffix in publishMove
(e.g., "e8q" -> "e8" + QUEEN)
- Add game end overlay with victory/defeat/draw celebration
- Remove all debug println statements for production readiness

- Add ChessLobbyState with completedGames, replaceGameState(), moveToCompleted()
- Add challengerAvatarUrl to ChessChallenge
- Add CompletedGame data class for game history
Platform Adapters:
- AndroidChessAdapter: AndroidChessPublisher, AndroidRelayFetcher, AndroidMetadataProvider
- DesktopChessAdapter: DesktopChessPublisher, DesktopRelayFetcher, DesktopMetadataProvider
Shared Infrastructure:
- ChessRelayFetchHelper for one-shot relay queries
- IUserMetadataProvider interface for platform-specific metadata
- ChessFilterBuilder with simple filter methods for fetchers
- ChessSubscriptionController interface for subscription management
Fix ChessSubscription.kt to remove broken dataSources().chess reference
(subscriptions now managed by ChessLobbyLogic)
