feat(serverless): add processing time to CollectionsService responses

[qdrant-cloud-bot]

Summary

• Add double time (with the standard “Time spent to process” comment) to all qdrant.serverless.CollectionsService response messages: CreateCollectionResponse, DeleteCollectionResponse, GetCollectionResponse, ListCollectionsResponse.
• Regenerate Go / Python / TypeScript bindings.

Field numbers use the next free tag on each message (3 or 4) because existing fields already occupy tag 2, matching how Qdrant’s own ScrollResponse places time when needed.

Test plan

• make generate / make lint clean
• Downstream qdrant-serverless collection-manager fills time on success paths
• Rust / Python clients pick up the new field after syncing this proto
