docs(priorities): refresh planner queue for 3777

[asim]

Summary:

• Promote Fix atlascloud universe concierge buyer notification recipient #3772 as the top live atlascloud universe blocker.
• Drop Fix atlascloud plan-delegate flow completion timeout after delegated notify #3766 from the queue because PR Fix plan-delegate timeout completion #3774 shipped the post-side-effect timeout handling.
• Keep Fix atlascloud plan-delegate harness missing delegated notify side effect #3760, Isolate file-store tests from shared default directory #3751, Propagate agent run cancellation and deadlines through model and tool calls #3544, Emit OpenTelemetry spans for agent run timelines #3525, and interop: AP2 (Agent Payments Protocol) support — mandate layer over A2A + x402 #3552 ranked by roadmap phase and adoption value.

Testing:

• go build ./...
• go test ./... (fails in this environment: loopback targets forbidden in client/grpc and transport/grpc)
• golangci-lint run ./...

Closes #3777
