feat(ipuaro): add session configuration

- Add SessionConfigSchema with persistIndefinitely, maxHistoryMessages, saveInputHistory
- Implement Session.truncateHistory() method for limiting message history
- Update HandleMessage to support history truncation and input history toggle
- Add config flow through useSession and App components
- Add 19 unit tests for SessionConfigSchema
- Update CHANGELOG.md and ROADMAP.md for v0.22.2
