🎉 FileBox v2 plugin system fully working with TLV encoding fix

Major achievements:
- Fixed TLV encoding format to match plugin expectations
  - Header: version(2 bytes) + argc(2 bytes)
  - Entry: tag(1) + reserved(1) + size(2) + data
- Removed duplicate implementation in method_dispatch.rs
- All FileBox methods working: open/read/write/close
- Successfully tested file I/O operations

This completes the v2 plugin system integration for FileBox.
