Drop the broad `tools/*.{js,ts}` globs from the `frontend` filter so
edits to CI-only or backend helper scripts in `tools/` stop triggering
frontend and e2e jobs. Only `tools/generate-svg.ts` is kept.
Also renames `tools/lint-pr-title.js` to `.ts` for consistency, drops
the empty root `*.js` glob, fixes stray indentation in the `dockerfile`
filter and adds missing `setup-node`.

## Summary
- Enforce **Conventional Commits** on PR titles (PRs are squash-merged,
so the PR title becomes the final commit message).
- Add a local `make lint-pr-title` target so contributors can validate
titles before pushing.
## Why
We squash-merge PRs, which means the final repository history is largely
shaped by **PR titles**. Enforcing a consistent Conventional Commits
format makes:
- **Release notes & changelogs easier to generate** (types like `feat` /
`fix` can be grouped automatically).
- **History easier to scan** (uniform structure, optional scopes,
explicit breaking changes via `!`).
- **Automation more reliable** (future tooling can infer category and
scope from the title).
## PR title format
```text
type(scope)!: subject
type: one of build|chore|ci|docs|feat|fix|perf|refactor|revert|style|test
scope: optional (e.g. web, api, actions, repo, …)
!: optional, indicates a breaking change
subject: short, imperative, no trailing period
```
## Examples
```text
feat(web): add dark mode toggle
fix(api): avoid panic when repo is missing
chore(ci): lint PR titles with commitlint
refactor(templates): reduce duplication in repo list rendering
feat!: remove legacy OAuth endpoint
```
## Local testing
```text
make deps-frontend
make lint-pr-title PR_TITLE="feat(web): add dark mode toggle"
```
