chore: update .gitignore with tzj/vs_offload configuration

- Add Claude Flow generated files ignore patterns
- Add test data directory ignore
- Add Serena MCP tool config ignore
- Add Windows wrapper files ignore

These configurations improve development workflow by excluding temporary
and generated files from version control.
