feat: introduce Forever Mode with A2A listener

- Sisyphus: auto-resume timer with schedule_work tool
- Confucius: built-in sub-agent for knowledge consolidation before compression
- Hippocampus: in-memory short-term memory via background micro-consolidation
- Bicameral Voice: proactive knowledge alignment on user input
- Archive compression mode for long-running sessions
- Onboarding dialog for first-time Forever Mode setup
- Refresh system instruction per turn so hippocampus reaches the model
- Auto-start A2A HTTP server when Forever Mode + Sisyphus enabled
- Bridge external messages into session and capture responses
- Display A2A port in status bar alongside Sisyphus timer
