Add Batch Get Collection Version File Paths to SysDB API

This PR introduces a new batch API to retrieve version file paths for multiple collections in SysDB, which is necessary for operations like garbage collecting collections in fork trees. The change spans both Rust and Go components, defining new proto messages and service endpoints, implementing the server, coordinator, and DAO methods, providing tests, and adding error handling for batch retrieval.

Key Changes:
• New proto messages and SysDB RPC method (BatchGetCollectionVersionFilePaths) added to idl/chromadb/proto/coordinator.proto
• Rust Sysdb adds batch_get_collection_version_file_paths method, including error enum and wiring through GRPC and test implementations
• Go code: Implements coordinator, service, DAO, and model interfaces for batch retrieval of collection version file paths
• Updates Go mocks, new unit/integration test in coordinator_test.go
• Integration with both test and actual data paths for version files in collection data models

Affected Areas:
• SysDB API (Rust & Go)
• Protobuf interface definition
• Rust sysdb.rs and test_sysdb.rs
• Go coordinator, catalog, DAO, mock, test layers

Potential Impact:

Functionality: Enables efficient retrieval of version file paths for batched collection IDs, improving garbage collection workflows. No breaking changes to existing APIs.

Performance: Batch fetch is more efficient for clients. Current Go implementation uses IN queries, which may have DB/backend limitations for very large batches (see code TODO).

Security: No direct security impact; assumes existing API authentication applies.

Scalability: Scales better than single-fetch-per-collection but might bottleneck on database IN queries for very large batch sizes; further optimization noted as a TODO.

Review Focus:
• Batch query implementation in Go DAO (possible IN clause scalability)
• Error handling and proto/Rust error propagation
• Interface contract between proto, Go, and Rust layers for batch calls
• Correctness of test coverage and edge cases
