feat: optimize docker builds (#10925)
* feat(docker): optimize Dockerfile for faster builds

- add BuildKit syntax directive for advanced caching features
- implement cache mounts for Go modules and build cache
- reduce layers by combining RUN commands (5→2 in final stage)
- optimize apt-get with --no-install-recommends flag
- use COPY --chmod to avoid separate permission fixing

Performance improvements:
- incremental builds after code changes: ~8.6x faster (1m51s → 13s)
- go module/build cache persists between builds
- reduced layer count improves cache efficiency

* ci: optimize Docker builds with BuildKit caching

- enable BuildKit with GitHub Actions cache backend
- add Docker Hub registry cache for cross-workflow sharing
- move Docker login earlier to enable registry cache writes
- use dual cache strategy (gha + registry) for faster builds

expected improvements:
- PR builds can reuse main branch cache from Docker Hub
- rebuild after code changes ~5-10x faster with persistent cache
- cross-PR cache sharing reduces redundant builds
