Summary

• The resume guard error names the collect path for the surface it runs on: wait_agents where mounted (exec primary), mailbox mail where not (TUI, nested)
• The resume_agent and wait_agents descriptions state the no-prior-report rule and the exec-only mount

Verification

• bun run check passes (lint, typecheck, build, 8336 tests across 538 files)
• New co-located unit test asserts the guard text branches by mount
