- Enhanced AGENTS.md to include post-editing commands for Go code, specifying the use of `gofmt -w`, `go vet ./...`, and `scripts/lint-go.ps1`.
- Updated engineering rules in .cursor/rules/engineering.mdc to clarify the linting process and ensure consistency in Go code formatting.
- Improved documentation for CI checks related to Go code style and linting.
