[Codename-11]

Summary

• replace stale/MCP-quiet Delivery dead ends with typed Still working, Resume session, and Abandon session actions
• surface the same recovery controls on issue detail and route generic asks into a prepared issue reply
• keep operator confirmation separate from MCP/runtime heartbeat evidence and clarify that Dismiss card only clears the presentation

Validation

• pnpm ci:local:quality (1,523 passed, 1 skipped)
• pnpm exec playwright test tests/e2e/command-center-attention-actions.spec.ts --workers=1
• focused Vitest coverage for presentation, authorization, lifecycle evidence, and stale-sweep grace

Delivery

Implements AXI-164.

No merge, release, or deployment is included.
