build(gesture): fetch MediaPipe wasm + model at install/build instead of committing

The self-hosted gesture assets (~27MB of wasm runtime + gesture_recognizer.task)
were committed to the repo. Replace that with scripts/fetch-gesture-assets.mjs,
which downloads them into src/web/public/gesture/ — idempotent (skips existing)
and non-fatal (the overlay is opt-in via CODEMAN_GESTURE=1, so a fetch failure
only warns). Wired into:
  - postinstall.js (dev: populates src/web/public/gesture for `npm run dev`)
  - build.mjs (before `cp -r src/web/public dist/web/`, so prod/dist gets them)

The files are already covered by the bare `public` .gitignore rule, so they
stay untracked. The overlay bundle (gesture-codeman.js) remains committed — it's
built from a separate repo and is small. Pin @mediapipe wasm to 0.10.21 to match
the bundled tasks-vision API.
