feat: context rot defense for /ship — subagent isolation + clean step numbering (v0.18.1.0) (#1030)

* refactor: renumber /ship steps to clean integers (1-20)

Replaces fractional step numbers (1.5, 2.5, 3.25, 3.4, 3.45, 3.47, 3.48,
3.5, 3.55, 3.56, 3.57, 3.75, 3.8, 5.5, 6.5, 8.5, 8.75) with clean
integers 1 through 20, plus allowed resolver sub-steps 8.1, 8.2,
9.1, 9.2, 9.3. Fractional numbering signaled "optional appendix" and
contributed to /ship's habit of skipping late-stage steps.

Affects:
- ship/SKILL.md.tmpl (all headings + ~30 cross-references)
- scripts/resolvers/review.ts (ship-side 3.47/3.48/3.57/3.8 conditionals)
- scripts/resolvers/review-army.ts (ship-side 3.55/3.56 conditionals)
- scripts/resolvers/testing.ts (ship-side 2.5/3.4 references, 5 sites)
- scripts/resolvers/utility.ts (CHANGELOG heading gets Step 13 prefix)
- test/gen-skill-docs.test.ts (5 step-number assertions updated)
- test/skill-validation.test.ts (3 step-number assertions updated)

/review step numbering (1.5, 2.5, 4.5, 5.5-5.8) intentionally unchanged —
only the ship-side of each isShip conditional was updated.

* feat: subagent isolation for /ship's 4 context-heaviest sub-workflows

Fights context rot. By late /ship, the parent context is bloated with
500-1,750 lines of intermediate tool output from tests, coverage audits,
reviews, adversarial checks, and PR body construction. The model is
at its least intelligent when it reaches doc-sync — which is why
/document-release was being skipped ~80% of the time.

Applies subagent dispatch (proven pattern from Review Army at Step 9.1
and Adversarial at Step 11) to four sub-workflows where the parent
only needs the conclusion, not the intermediate output:

- Step 7 (Test Coverage Audit) — subagent returns coverage_pct, gaps,
  diagram, tests_added
- Step 8 (Plan Completion Audit) — subagent returns total_items, done,
  changed, deferred, summary
- Step 10 (Greptile Triage) — subagent fetches + classifies, parent
  handles user interaction and commits fixes (AskUserQuestion + Edit
  can't run in subagents)
- Step 18 (Documentation Sync) — subagent invokes full /document-release
  skill in fresh context; parent embeds documentation_section in PR body

Sequencing fix for Step 18: runs AFTER Step 17 (Push) and BEFORE Step 19
(Create PR). The PR is created once from final HEAD with the
## Documentation section baked into the initial body — no create-then-
re-edit dance, no race conditions with document-release's own PR body
editor.

Adds "You are NOT done" guardrail after Step 17 (Push) to break the
natural stopping point that currently causes doc-release skips.

Each subagent falls back to inline execution if it fails or returns
invalid JSON. /ship never blocks on subagent failure.

* test: regression guard for /ship step numbering

Three regression guards in skill-validation.test.ts to prevent future
drift back to fractional step numbering:

1. ship/SKILL.md.tmpl contains no fractional step numbers except the
   allowed resolver sub-steps (8.1, 8.2, 9.1, 9.2, 9.3). A contributor
   adding "Step 3.75" next month will fail this test with a clear error.

2. ship/SKILL.md main headings use clean integer step numbers. If a
   renumber accidentally leaves a decimal heading, this catches it.

3. review/SKILL.md step numbers unchanged — regression guard for the
   resolver conditionals in review.ts/review-army.ts. If a future edit
   accidentally touches the review-side of an isShip ternary, /review's
   fractional numbering (1.5, 4.5, 5.7) would vanish. This test catches
   that cross-contamination.

* docs: sync ship step references after renumber

CLAUDE.md: "At /ship time (Step 5)" → "(Step 13)" — CHANGELOG is now
  explicitly Step 13 after the renumber (was implicit between old
  Step 4 and Step 5.5).
TODOS.md: "Step 3.4 coverage audit" → "Step 7" — references the open
  TODO for auto-upgrading ★-rated tests, which hooks into the coverage
  audit step.

Both are historical references to ship's step numbering that became
stale when clean integer renumbering landed in 566d42c2.

* test: update golden ship skill baselines after renumber + subagent refactor

The golden fixtures at test/fixtures/golden/{claude,codex,factory}-ship-SKILL.md
regression-test that generated ship/SKILL.md output matches a committed baseline.
After renumbering steps to clean integers and converting 4 sub-workflows to
subagent dispatches, the generated output changed substantially — refresh the
baselines to reflect the new expected output.

* chore: bump version and changelog (v0.18.1.0)

* chore: gitignore Claude Code harness runtime artifacts

.claude/scheduled_tasks.lock appears when ScheduleWakeup fires. It's a
runtime lock file owned by the Claude Code harness, not project source.
Add .claude/*.lock too so future harness artifacts in that directory
don't need their own gitignore entries.

> You are running a ship-workflow test coverage audit. Run `git diff <base>...HEAD` as needed. Do not commit or push — report only.

**Parent processing:**
1. Read the subagent's final output. Parse the LAST line as JSON.
2. Store `coverage_pct` (for Step 20 metrics), `gaps` (user summary), `tests_added` (for the commit).
3. Embed `diagram` verbatim in the PR body's `## Test Coverage` section (Step 19).
4. Print a one-line summary: `Coverage: {coverage_pct}%, {gaps} gaps. {tests_added.length} tests added.`

**Sequencing:** This step runs AFTER Step 17 (Push) and BEFORE Step 19 (Create PR). The PR is created once from final HEAD with the `## Documentation` section baked into the initial body. No create-then-re-edit dance.

## Step 8.5: Auto-invoke /document-release
After the PR is created, automatically sync project documentation. Read the
`document-release/SKILL.md` skill file (adjacent to this skill's directory) and
execute its full workflow:
1. Read the `/document-release` skill: `cat ${CLAUDE_SKILL_DIR}/../document-release/SKILL.md`
2. Follow its instructions — it reads all .md files in the project, cross-references
the diff, and updates anything that drifted (README, ARCHITECTURE, CONTRIBUTING,
CLAUDE.md, TODOS, etc.)
3. If any docs were updated, commit the changes and push to the same branch:
```bash
git add -A && git commit -m "docs: sync documentation with shipped changes" && git push
```
4. If no docs needed updating, say "Documentation is current — no updates needed."
This step is automatic. Do not ask the user for confirmation. The goal is zero-friction
doc updates — the user runs `/ship` and documentation stays current without a separate command.
If Step 8.5 created a docs commit, re-edit the PR/MR body to include the latest commit SHA in the summary. This ensures the PR body reflects the truly final state after document-release.
