feat(session): implement session reset policy for messaging platforms

- Added configuration options for automatic session resets based on inactivity or daily boundaries in cli-config.yaml.
- Enhanced SessionResetPolicy class to support a "none" mode for no auto-resets.
- Implemented memory flushing before session resets in SessionStore to preserve important information.
- Updated setup wizard to guide users in configuring session reset preferences.
