- Add SessionStateManager (server/services/session-state.ts) as source
of truth for agent status, tools, approvals, and notifications
- Integrate into terminal server with state patches broadcast via WS
- Add /add-approval and /resolve-approval endpoints so approval
lifecycle is tracked centrally and broadcast to all clients
- Add permissionMode field to AgentSessionState
- Frontend store (session-state.ts) + WS service (session-state-ws.ts)
consume snapshots and patches from terminal server (4103)
- Rewrite useGlobalApproval to derive pending approvals from
centralized state — resolving on one client now clears all others
- Migrate useTranscriptDebug: processing, hookMeta, serverRegistry
now derived from session state store; remove 5s registry polling
- hooks-approval.ts notifies terminal server on add/resolve
