Contributed to the denoland/typescript-go repository by delivering two targeted features focused on CI/CD optimization and code maintainability. Disabled the create-cache GitHub Actions workflow by commenting out its YAML configuration, effectively halting unnecessary scheduled, push, and manual runs to conserve resources and reduce CI pipeline noise. Refactored the findallreferences.go file to standardize symbol access, introducing a Get method for map-like lookups and an Iter method for exports iteration, which improved the consistency and robustness of exported symbol handling. Leveraged Go and YAML, applying skills in code refactoring and CI/CD to enhance maintainability and future-proof symbol resolution tooling.
