chore(deps): bump @types/node to ^25.9.1 (#14)

* chore(deps): bump @types/node to ^25.9.1

Align @types/node to fleet-latest major (v25; 7 active repos already on 25). Deps resolve clean (pnpm install). CI gates build+test. Part of the
2026-05-23 fleet major-version alignment sweep.

* ci: pin commitlint.yml actions to SHAs (org ruleset requires full-length SHA)

Pre-existing infra issue blocking all PRs to this repo: actions/checkout@v4 and
wagoid/commitlint-github-action@v6 are unpinned; the org ruleset rejects them.
Pin to the SHAs the sibling bfx-api-node-rest already uses.
