Quality-improve 10 v7.0.0-era engineering skills
Applies three consistent fixes across the v7.0.0 batch:
- Rename `## Output Structure` → `## Output Format` for consistency
- Wrap output template in `---` document separators (code-review-checklist,
debugging-log-analyser needed full structural upgrade; remaining 8 already
had the wrapper)
- Remove `## Example Trigger Phrases` section from all 10 skills
Skills updated: code-review-checklist, debugging-log-analyser,
changelog-generator, pr-description-writer, system-design-interview,
test-strategy-doc, runbook-writer, incident-postmortem, api-docs-writer,
architecture-decision-record
Both `skills/` and `plugins/pm-engineering/skills/` copies synced.
