ci: scope PR workflow runs by changed paths (#1067)
## 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.

feature works

## 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.
