v2.0.14: Go live — real engine, session persistence, slash commands, UX polish

Critical fixes:
- Remove mock engine entirely (~600 lines), connect to real Rust engine via --headless
- Fix JSON-RPC protocol: Action enum tuple→struct variants for serde deserialization
- Add 6 missing UiEvent variants (Banner, StatusUpdate, SystemMessage, SidebarUpdate, ModelInfo, ContextFilesUpdate)
- Session persistence across turns — AI remembers previous exchanges
- Wire all 63+ slash commands through headless orchestrator (was no-op)
- Fix empty call_id in tool_call_end — tool cards no longer stuck as "running"
- StatusUpdate emissions from worker (thinking → tool_name → idle)
- Emit Banner + StatusUpdate on engine startup

UX polish (Claude Code-style):
- "Cooked for Xm Xs" session timer after each AI response
- Compact single-line tool cards for completed tools
- Assistant messages with filled circle bullet indicator
- User messages with chevron prompt
- System messages with distinct level icons (info/warning/error)
