Context-enabled sg-bucket APIs

Dependencies

• CBG-5290: Pass context through all methods couchbase/sg-bucket#144

[Copilot]

Pull request overview

This PR updates Rosmar’s sg-bucket integration to use context-enabled APIs, aligning bucket/collection operations, feeds, views, queries, and tests with the new context.Context-passing method signatures.

Changes:

• Updated Rosmar bucket/collection implementations to accept context.Context in sg-bucket interface methods (CRUD, query, design docs, subdoc, feeds, vbno, etc.).
• Updated feed callback signatures and internal feed/checkpoint operations to pass context through.
• Updated tests to use t.Context() and to call the new context-aware APIs.

there's already a context.TODO() above so you don't have to do context.Background() . I'd be fine if you want to actually add a context here and change the API, but I don't think it would gain much.
