fix(ci): fix golangci-lint version, skip player test in CI, remove standalone frontend build

- Use specific golangci-lint version (v2.5.0) instead of 'v2' which
  the action cannot parse
- Use --build-tags flag (v2 syntax) instead of -tags
- Skip player test in CI: requires Wails runtime context and audio
  device which are unavailable in GitHub Actions
- Remove standalone 'pnpm build' from frontend job since Vite cannot
  resolve Wails path aliases alone; the build-check job validates the
  full build via Wails
