Subject: [PATCH] ci: add GitHub Actions CI for web and pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The repo had no .github/workflows/, so nothing ran on PRs. Add a CI
workflow with two jobs built from the project's real commands:

- web: npm ci, npx tsc --noEmit (no typecheck script exists), vitest,
  eslint, next build — scoped to web/ via working-directory.
- pipeline: pip install -r requirements.txt, pytest tests/ (190 tests,
  hermetic — render/network paths are mocked). soundfile bundles
  libsndfile in its wheel, so no apt step is needed.

House style: name CI, push+PR to main, concurrency with
cancel-in-progress, contents:read, pinned actions with dep caching.
Validated with actionlint.
