Subject: [PATCH 1/2] fix(config): handle UTF-8 BOM in configuration file
 loading

Problem:
On Windows, some text editors (like Notepad) automatically add UTF-8 BOM
to JSON files when saving. This causes json.decoder.JSONDecodeError:
"Unexpected UTF-8 BOM" and AstrBot fails to start when cmd_config.json
contains BOM.

Solution:
Add defensive check to strip UTF-8 BOM (\ufeff) if present before
parsing JSON configuration file.

Impact:
- Improves robustness and cross-platform compatibility
- No breaking changes to existing functionality
- Fixes startup failure when configuration file has UTF-8 BOM encoding

Relates-to: Windows editor compatibility issues
