Subject: [PATCH] Add @skip_if_rust_bson to tests for unimplemented Rust
 features

- TestRawBatchCursor and TestRawBatchCommandCursor (RawBSONDocument not implemented)
- TestBSONCorpus (BSON validation/error detection not fully implemented)
- test_uuid_subtype_4, test_legacy_java_uuid, test_legacy_csharp_uuid (legacy UUID representations not implemented)

These features are not implemented in the Rust extension and would require
significant additional work. Skipping these tests prevents 35 failures.
