SSE resumes from 'now' after a reconnect — it never replays events that streamed while the connection was down (mobile OS idle kill during a long thinking gap, LAN blip, app backgrounding). The old resync only recovered busy->idle transitions, so tokens that arrived during the gap were lost forever and the answer appeared 'cut'. - sessions.ts: add catchUpSessionMessages() — re-fetch the current session's messages/parts and merge with on-screen state, preserving temp- optimistic placeholders (established loadOlderMessages merge pattern). - events.ts: fire the catch-up once per re-established stream, alongside the existing busy-session resync.

Problem
SSE does not replay events that streamed while the connection was down (mobile OS idle kill during long thinking gap, LAN blip, backgrounding). Tokens arriving during the gap were lost forever — answers appeared 'cut'. The existing resync only recovered busy→idle transitions, not answer content.
