fix: invalidate cache on each commit to force source build

- Add github.sha to cache key to ensure fresh builds per commit
- Prevents using cached v1.4.0 binary that lacks semicolon support
- Forces Install GoSQLX step to run and detect local repository
- Ensures tests run against current PR code changes
