Refactor round: ship web/index.html, drop the remote browser, fix stale comments and README

- `.gitignore` said `index.html` unanchored, which also caught the Vite source page;
  a fresh clone could neither `dev` nor `build`. Anchored to `/index.html`, page added.
- Removed GM_REMOTE (tools/remote/gm-browser.ps1 and the ssh/scp branch in browser.mjs):
  the Windows test machine is gone and the only flaky check that lived on it is closed (#37).
- Removed `npm run preview`, undocumented and unused.
- Comments: wrong number in collider.test.ts (250 → 200), the "declarations used to…"
  history in listItems.ts and friends, the 24 px/28 contradiction, section banners in
  nodes/index.ts, node-catalog.test.ts and api/index.php, name paraphrases, and the stale
  step numbers in tools/e2e/11-…23- from the old global count.
- README: asset types include `animation`, kind order Number/Text/Boolean, tagged colour
  and texture items, 6/5 kinds, the `Texture` node, `./build.sh`, PROJECT_FORMAT_VERSION,
  and the file tree (kinds.ts, listItems.ts, propertyPorts.ts, Breadcrumb.ts, beads.ts,
  tools/assets/).
- tests/helpers.ts takes the duplicated `findObject` and `sceneWithCamera`.

Proof: ./check.sh 797 tests, full e2e ALL PASSED 633 checks against this bundle.
