refactor(cli): Remove debug logger statements

Clean up debug logging in hooks:
- Remove mock mode and streaming logs from use-send-message
- Remove theme change event logs from use-system-theme-detector
- Add project-files.ts for logger utilities

These logs were used for development debugging and are no longer needed.
