Major reliability improvements to the message processing pipeline:
- Add messages.seq monotonic cursor replacing timestamp-based cursors,
preventing message loss from timestamp collisions with LIMIT queries
- Add work_items table separating agent production from delivery,
enabling delivery retry without re-running the agent
- Propagate Discord send failures instead of silently swallowing them
- Add Claude 429 → Kimi K2.5 automatic provider fallback with cooldown
- Fix follow-up turn state reset in live index.ts path (not just
message-runtime.ts) to prevent final output from being lost
- Add restart context tracking for graceful restart announcements
- Lazy migration from timestamp cursors to seq cursors for existing data

Two bugs fixed:
1. agent-runner error path race condition: when agent process exited
with error, the promise resolved immediately without waiting for
outputChain, allowing a late wrappedOnOutput to re-persist a stale
session ID after clearSession had already run.
2. follow-up turn state not resetting: when a follow-up IPC message
joined an active run, turn-level flags (finalOutputSentToUser,
sawNonProgressOutput) from the first turn prevented the last
progress from being promoted to a final message.
