Merge branch 'main' into dev

Surgical merge of 74 commits from main into dev. Key features ported:

- Provider visibility gating (appVersion filtering for Pi/Copilot)
- Pi agent provider + Copilot re-enabled
- Provider-declared features system (Codex fast mode)
- Workspace dedup by worktree root (adapted to integer IDs)
- Bulk close archiving fix for stored agents
- Agent creation timeout increase to 60s
- Audio/voice crash fixes (external buffer copies)
- Multi-host setup fix
- Reload agent tab action

Dev architecture preserved: SQLite storage, service proxy,
workspace setup dialog, hover cards, removed launcher tabs.
