* feat(macos): adopt shared read-only chat transcript cache
Cache-first cold open for the macOS chat window/panel: the last known
transcript and session list paint immediately from the shared SQLite
transcript cache, then live gateway history replaces them wholesale.
Recent chats stay browsable read-only while the gateway is unreachable;
sending remains gated by connection state.
- Wires OpenClawChatSQLiteTranscriptCache into WebChatSwiftUIWindowController;
DB at ~/Library/Application Support/OpenClaw/chat-cache.sqlite.
- Gateway identity (MacChatTranscriptCache.gatewayID), derivable offline:
local keys on the canonical gateway state dir; remote/direct keys on the
full canonical URL (scheme, host, resolved port, percent-encoded
path/query); remote/ssh keys on the SSH target plus the resolved remote
gateway port, mirroring the tunnel port resolution. Unconfigured mode
gets no cache.
- macOS file protection: no per-file Data Protection classes; iOS-only
attribute stays gated behind #if os(iOS) in the shared store, and the
per-user container plus FileVault protect at rest.
- Onboarding chat stays uncached (transient guided setup session).
