Count a background job as the wakeup behind an ETA, and call the time an estimate

[EdbertChan]

Summary

A background command that exits when its job finishes now counts as the wakeup behind an ETA, and the named time is called an estimate.

The guard that enforces this already accepts that kind of exit. The written rule named only the scheduled-wakeup tool, so rule and guard disagreed.

Review Claim

The waiting rule now matches what the guard actually accepts as a wakeup for a background job.

Review Lane

Review Unit

Safety Invariant

An ETA still needs a live wakeup; the hook's behavior is unchanged and the test runs its real decision function.

Slice Rationale

One rule and the test that ties it to the hook.

Non-goals

• No change to the wait-needs-wakeup hook.

Test Plan

Test Plan

• python3 -m unittest tests.test_cat_mode: the new TestCatModeEtaMatchesWaitHook checks fail before the prose change and pass after; cat-mode stays at 299 of 300 lines
• Every step in .github/workflows/ci.yml ran locally on the full stack with rc=0: run_all_tests.sh, check_no_tracked_local_artifacts, check_hook_test_coverage, check_no_silent_hook_except, check_rules_are_wired, check_skills_three_harnesses, check_ecosystem_boundaries, check_skill_file_refs, check_skill_test_coverage, check_skill_test_debt_no_growth, check_skill_trigger_mechanism, check_dora_baseline, check_no_dated_provenance, check_no_new_comments, ruff check . --select E9,F, shellcheck install.sh

Revert Plan

Revert Plan

• Safe to revert? Yes
• Revert command: git revert <sha>
• Post-revert steps: rerun ./install.sh so installed copies match
• Data migration? No
