merge: resolve conflicts with master, add inbound attachment materialization

- Delete localagent.py and test_difysvapi_runner.py (replaced by plugins)
- Keep master's tool loader enhancements (byte_offset, encoding params)
- Remove feature branch's artifact reference code (use sandbox paths instead)
- Add _materialize_inbound_attachments in orchestrator for sandbox file staging
- Keep master's test formatting and new tests
- Keep master's frontend refactoring
