Rename doc-* mise tasks to docs-check-* / docs-review-* (#113)

## Summary
- Rename 4 automated-check tasks: `doc-titles` → `docs-check-titles`, `doc-filenames` → `docs-check-filenames`, `doc-links` → `docs-check-links`, `doc-index` → `docs-check-index`
- Rename 3 interactive-review tasks: `doc-random` → `docs-review-random`, `doc-tags` → `docs-review-tags`, `doc-stale` → `docs-review-stale`
- Update all references in `.pre-commit-config.yaml`, `ai-assistance-guide.md`, and `review-documentation.md`
- Historical changelog entries left as-is

## Test plan
- [x] `mise run docs-check-titles` exits 0
- [x] `mise run docs-check-links` exits 0
- [x] `mise run docs-review-tags` exits 0
- [x] `mise run doc-titles` fails with "no task found"
- [x] All pre-commit hooks pass (including renamed hook IDs)
