## Description
Makes PR workflow runs more selective by routing docs-only changes to
docs validation instead of the full CI workflow, while preserving
workflow validation and existing code/e2e/release gates for applicable
changes.
## Type of Change
- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [x] Code refactoring (no functional changes)
## Changes Made
- Added `pull_request.paths-ignore` to `.github/workflows/ci.yml` so
docs/wiki/markdown-only PRs do not queue the general CI workflow.
- Removed `.github/workflows/ci.yml` from the CI internal `code` path
filter so CI-only workflow edits can run workflow validation without
forcing Python/Rust code jobs.
- Added a docs PR validation job to `.github/workflows/docs.yml` for
`docs/**`, `wiki/**`, `mkdocs.yml`, and docs workflow changes.
- Reduced default docs workflow token permissions to `contents: read`,
with `contents: write` scoped only to the deploy job.
- Added docs workflow dry-runs to `scripts/validate-workflows.sh` so
local/CI workflow validation covers the new PR and manual docs paths.
## Testing
- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [ ] New tests added for new functionality
- [x] Manual testing performed
### Test Output
```text
$ actionlint .github/workflows/ci.yml .github/workflows/docs.yml
# no output
$ act pull_request -W .github/workflows/docs.yml -n
*DRYRUN* [Deploy Documentation/validate] 🏁 Job succeeded
$ act workflow_dispatch -W .github/workflows/docs.yml -n
*DRYRUN* [Deploy Documentation/deploy] 🏁 Job succeeded
$ act pull_request -W .github/workflows/ci.yml -n
*DRYRUN* [CI/changes] 🏁 Job succeeded
*DRYRUN* [CI/commitlint] 🏁 Job succeeded
$ python -m mkdocs build
INFO - Documentation built in 1.28 seconds
$ bash scripts/validate-workflows.sh
# completed successfully; act dry-runs passed. Some unsupported runner-platform matrix entries are skipped by local act, as before.
$ git diff --check
# no output
```
## Real Behavior Proof
- Environment: Windows local checkout, branch `smart-pr-runs`, `act`
0.2.87, temporary local `actionlint` installed via `go install`.
- Exact command / steps: Ran `actionlint` against changed workflows,
`act` dry-runs for docs PR/manual paths and CI PR path, actual `python
-m mkdocs build`, full `scripts/validate-workflows.sh`, and `git diff
--check`.
- Observed result: Changed workflows lint cleanly; docs PR and manual
docs workflow paths dry-run successfully; CI PR dry-run still covers
`changes` and `commitlint`; MkDocs builds; repository workflow
validation script completes with the new docs dry-runs included.
- Not tested: Full non-dry-run GitHub Actions execution on hosted
runners before PR creation.

## Screenshots (if applicable)
N/A.
## Additional Notes
- No issue is linked because this PR was not opened for a specific
tracked issue.
- `mkdocs build` reports existing docs/nav warnings but exits
successfully; strict mode currently fails on existing warnings, so the
PR validation uses the deploy-compatible non-strict build.
- Python unit/lint/type checks are not applicable to this workflow-only
change.
`CI / lint (pull_request)` failed because `ruff format --check` detected
formatting drift in the new PR governance script and its tests. This PR
aligns those files with repository formatting rules so the lint job can
pass.
- **Root cause**
- `ruff format --check .` reported two files as non-canonical:
- `scripts/pr-governance.py`
- `scripts/tests/test_pr_governance.py`
- **Change set**
- Applied `ruff` formatting to only the two flagged files.
- No behavioral or logic changes; edits are line-wrap/format
normalization only.
- **Representative update**
```python
parser.add_argument(
"--event", type=Path, required=True, help="Path to the GitHub event
payload JSON."
)

scripts/validate-workflows.sh exercises release.yml with an `act`
dry-run that posted a synthesized push-to-main event. After the
previous commit retired that trigger in favor of `release:
published`, the dry-run started failing in CI because release.yml
no longer responds to push events.
Simulate the new trigger instead: feed release.yml a
release-published event (.github/act/release-published.json) and
move the push-to-main dry-run onto release-please.yml — the
workflow that now owns that event.
Add a workflow-validation CI job that installs actionlint and act,
checks the release and Docker workflows against checked-in event
fixtures, and shares the same validation script developers can run
locally.
