Auto-reconnect crashed bridge processes in the background#103

Adds a new grep command that searches tools, resources, and prompts by name and description across all active MCP sessions. Supports regex matching (-E), case-sensitive mode (-s), and type filters (--tools, --resources, --prompts). Available as both a top-level command (all sessions) and session command (single session).

* Add recovery hints for crashed and expired sessions in session list Show actionable hints under crashed and expired sessions in `mcpc` output, similar to the existing hint for unauthorized sessions. https://claude.ai/code/session_01D6ovkixxWohRHXaJP7Hh3g * Remove extra text from crashed session hint https://claude.ai/code/session_01D6ovkixxWohRHXaJP7Hh3g --------- Co-authored-by: Claude <noreply@anthropic.com>
When enumerating sessions (e.g. `mcpc` or `mcpc grep`), crashed bridges are now automatically restarted in the background without blocking the command. A 10-second cooldown (connect timeout + 5s buffer) between restart attempts prevents rapid retries. The lastRestartAttemptAt timestamp is persisted in sessions.json and checked inside the file lock to avoid concurrent restart races. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Avoid restarting a bridge that just crashed — wait for the cooldown period after lastSeenAt to give the old process time to fully clean up and prevent socket conflicts in shared-home environments. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Introduce two new transient session states that give users visibility into bridge lifecycle transitions: - 'connecting': shown during initial `mcpc connect` before bridge is ready - 'reconnecting': shown when a crashed bridge is being auto-reconnected Both display as yellow filled dots (●) in human output and as string values in JSON output. Stale transient states (>10s with no PID) automatically fall back to 'crashed'. Also rename lastRestartAttemptAt → lastConnectionAttemptAt and autoRestartCrashedSessions → reconnectCrashedSessions to better reflect that this is a bridge reconnection, not a full session restart. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Resolve conflicts with PR #100 (grep command) and PR #105 (help fix): - Take main's grep.ts (more features: --instructions, -m, capability-aware) and re-apply reconnectCrashedSessions call - Take main's index.ts grep options - Export DisplayStatus/getBridgeStatus (used by grep.ts) with new states - Merge changelog entries https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86

Sessions with dead bridges may show as 'reconnecting' (auto-reconnect in progress) instead of 'crashed', depending on timing. Update the expired and failover tests to accept both states. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Move post-connection status management into the bridge process itself rather than setting 'active' prematurely in reconnectCrashedSessions(): - Bridge sets status='active' after successful MCP connection - Bridge detects session ID mismatch (server issued new ID instead of resuming) and marks session as 'expired' — prevents silently continuing with a different session identity - reconnectCrashedSessions() no longer sets 'active'; it only reverts to 'crashed' on startup failure if bridge didn't set a terminal status https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Include unauthorized sessions (alongside crashed) as candidates for background auto-reconnection. When multiple sessions share the same OAuth profile, one session refreshing the tokens allows others to reconnect — the bridge reads from the OS keychain on startup and picks up the refreshed tokens automatically. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Add a visual diagram showing all possible transitions between session states, including the new connecting and reconnecting states. Update the prose to reflect auto-reconnect behavior for crashed and unauthorized sessions. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Two fixes to detect expired MCP sessions faster: 1. Session ID mismatch detection now catches all non-resume cases, including when the server doesn't return any session ID at all (previously only detected when both old and new IDs were present). 2. Bridge sends first keepalive ping 5s after startup instead of waiting the full 30s interval, catching stale sessions early. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
Show 'reconnecting' as a single box with arrows from expired, unauthorized, and crashed converging into it. https://claude.ai/code/session_01FJXX4xys8aMoF4iVZbkC86
