- Replace manual checkpoint file writing with CLI's native /chat save command
- Add saveCheckpointViaCommand method to use CLI's built-in save functionality
- Deprecate saveSessionViaAcp as CLI doesn't support session/save ACP method
- Update saveCheckpoint to delegate to CLI command for complete context preservation
- Enhanced error logging in acpSessionManager session load
- Mark saveSessionViaAcp as deprecated with fallback to command-based save
- Fix ESLint errors: remove unused imports and catch variables, wrap case block declarations
This ensures checkpoints are saved with complete session context including tool calls,
leveraging CLI's native save functionality instead of manual file operations.
