Continuous autopilot mode with hourly planning

[gf5901]

Summary

• Continuous autopilot mode: Projects can now run in continuous mode (alongside the existing daily mode). In continuous mode, the Autopilot Lambda fires hourly and auto-approves plans — no human gate per plan. A timed cycle (configurable hours) runs until the window expires, the agent is fully blocked on human tasks, or a failure circuit breaker trips, at which point the cycle pauses and notifies via Discord.
• Plan keying: Plan sort keys changed from PLAN#YYYY-MM-DD to PLAN#YYYY-MM-DDTHH:MM:SS for continuous mode (backward-compatible — daily mode still uses date-only keys).
• Agent pacing: The planner can return next_check_hours (1–8) to defer the next invocation when no work is needed, avoiding unnecessary Opus calls.
• Cycle management API: New endpoints POST /cycle/start, POST /cycle/stop, POST /cycle/review for managing continuous cycles with feedback injection.
• Frontend: Mode selector (Off/Daily/Continuous), cycle controls, review panel with feedback, recent plan chips for continuous mode.
• SST app name fix: Config now reads SST_APP_NAME env var (defaults to agent-task-bot to match the deployed Pulumi stack).

Edge cases addressed

• Daily mode no longer blocks regenerate requests outside 07:00 UTC
• Lambda skips SSM trigger for continuous projects without an active cycle
• Cycle state is cleared when switching away from continuous mode
• Failure circuit breaker pauses the cycle after 3 consecutive high-failure plans
• Stale cycle_started_at can't cause immediate expiry when switching back to continuous
• Duplicate Regenerate button removed from continuous proposed view
• cycle/stop validates continuous mode before allowing stop

Test plan

• Python lint (ruff) passes
• Frontend typecheck passes
• API package typecheck + lint + tests pass
• Lambda deployed and health check returns OK
• Autopilot cron updated to hourly
• Manual: toggle Off → Daily → Continuous in the UI, verify mode persists
• Manual: start a cycle, verify plan is proposed within the hour
• Manual: stop cycle, provide feedback, restart — verify feedback appears in next plan context
