Introduce a standalone macOS menu-bar app (OSGKeyboardMac) that reuses the platform-agnostic OSGKeyboardShared core: record -> cloud/local ASR -> polish -> insert. Local mode uses Qwen3-ASR via mlx-swift-asr (macOS 15+, Apple Silicon); iOS targets stay zero-SPM. Harden iCloud sync for multi-device correctness: - Per-field settings merge (appSettings.v2) so concurrent edits no longer clobber each other's unrelated fields. - Per-device usage statistics (G-Counter) that sum instead of max(). - Tombstoned dictionary/history merge so deletes propagate and entries can't resurrect. - API keys replicate via iCloud Keychain, never iCloud KVS JSON; pulling a legacy blob without key fields no longer wipes local Keychain entries. - Add a low-risk "Sync Now" action in Settings. Fix Flow keyboard mic state: stay orange until the host publishes a real ready contract, share a single MicVoiceAvailability gate, and self-heal stale cross-process heartbeat jitter instead of getting stuck. Extract shared storage (SpeechHistoryStore/UsageStatisticsStore, ConfigurationStore) into OSGKeyboardShared and add tests for the new sync/merge logic.
