* fix: resolve webdav handshake error in permission checks
- Updated role permission logic to handle bidirectional subpaths,
fixing handshake termination by remote host due to path mismatch.
- Refactored function naming for consistency and clarity.
- Enhanced filtering of objects based on user permissions.
- Modified `makePropstatResponse` to preserve encoded href paths.
- Added test for `makePropstatResponse` to ensure href encoding.
* Delete server/webdav/makepropstatresponse_test.go
* ci(workflow): set GOPROXY for Go builds on GitHub Actions
- Use `GOPROXY=https://proxy.golang.org,direct` to speed up module downloads
- Mitigates network flakiness (e.g., checksum DB timeouts/rate limits)
- `,direct` provides fallback for private/unproxyable modules
- No build logic changes; only affects dependency resolution across all matrix targets
