refactor(go-lint): replace common-cache with actions/cache

Replace common-cache wrapper with direct actions/cache for golangci-lint
caching. This simplifies the action and improves performance.

Changes:
- Replace ivuorinen/actions/common-cache with actions/cache@v4.3.0
- Use hashFiles() for cache key generation instead of manual SHA256
- Simplify from 10 lines to 9 lines of YAML

Benefits:
- Native GitHub Actions functionality (no wrapper overhead)
- Better performance (no extra action call)
- Matches official golangci-lint-action approach
- Less maintenance (GitHub-maintained action)
- Reduces common-cache usage from 5 to 4 actions

Trade-off:
- Cache key format changes (invalidates existing caches once)
