Implements object manipulation capabilities for v0.11.0:
- CopyObject: server-side copy within/across buckets with metadata control
- DeleteObjects: batch delete up to 1000 objects in single request
Both operations follow AWS S3 API specification with proper:
- AWS Signature V4 signing
- XML request/response handling
- Content-MD5 and SHA256 headers
- Comprehensive input validation
Fixed DeleteObjects signature mismatch with MinIO by correcting the canonical
query string format for empty query parameter values (delete= instead of delete).
The writeQuery function now properly appends = to keys with empty values per
AWS Signature V4 specification.
CopyObject enables CLI mv commands. DeleteObjects enables efficient
batch operations for CLI sync/rm.
Tests: All CopyObject and DeleteObjects tests passing with MinIO.
