Merge origin/main into german/navara

Conflict resolutions:
- src/main.js: upstream's PHOTON_URL place-search setting is read once at
  module level and passed as geospatial: { endpoints: { photon } } by
  createApplication(), so every engine start of the switch flow gets it; the
  old single top-level createStandaloneApplication() call stays removed.
- src/layers/bikeshare/render/cesium/rendering.js: upstream's
  publishedCapacity fix applied with this branch's
  resolveCapacity(model, capacity, status) signature. The same fix is ported
  to src/layers/bikeshare/render/navara.js (record.publishedCapacity, status
  polls resolve from it), with a Navara regression test; upstream's
  proxyRoute test imports the moved render/cesium/rendering.js.
- src/layers/traffic/flow.js: upstream's nextTask() yield and current()
  check kept before the scene is taken from this branch's
  _trafficScene?.() ?? _viewer?.scene with its missing-scene return.
- scripts/package-boundaries.json, scripts/format-scope.json: union of both
  sides' file lists.
- src/voice/actionSchemas.test.mjs: both history comments kept, payload hash
  recomputed for the merged schemas (Sentinel-2 map stack enum plus the
  shorter layer alias hint).
- src/hudAltitudeDatum.test.mjs: this branch's engine-based IntelHUD
  construction with upstream's placeLabels summary context.

+### Path 4 — GitHub Codespaces (cloud, no local install)
+
+Codespaces requires a GitHub account. Overpass queries and OpenAI voice token
+requests return HTTP 403 through its forwarded HTTPS URL, even with API keys
+in `.env` and `GEV_ALLOWED_HOSTS` configured. Use a local setup for these features.
+
+The codespace runs the dev server in a cloud workspace, so Node and the dependencies
+never touch your machine. The globe still renders in your own browser, so it
+needs the same graphics there as any other path. GitHub Free includes 120
+core-hours a month with no card on file — about 60 hours on the default 2-core
+machine. Org and Enterprise plans include no free quota; current terms and
+quotas apply.
+
+1. Fork this repository, then open **your fork** on GitHub.
+2. Click the green **Code** button, the **Codespaces** tab, then **Create codespace on main**.
+3. In the codespace terminal:
+   ```bash
+   nvm install 24 && nvm use 24
+   npm ci
+   npm run doctor
+   GEV_ALLOWED_HOSTS="$CODESPACE_NAME-4173.$GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN" npm run dev
+   ```
+4. Open the **Ports** tab, find `4173`, and click the globe icon to open it in
+   the browser. The port is private by default, so the URL asks for your GitHub
+   login. Keep it private: a public port lets anyone use the app and the keys
+   in your `.env`.
+
+`GEV_ALLOWED_HOSTS` there is required, not optional. The dev server answers only
+the hostnames it trusts, and a forwarded port arrives on
+`$CODESPACE_NAME-4173.$GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN`. Without it the
+page is `Blocked request. This host is not allowed.` Leading-dot wildcards are
+ignored on purpose, so pass that exact name.
+
+⚠️ **A codespace is reachable from the internet.** Treat it as the
+wider-publish case in [Sharing an instance](#-sharing-an-instance). Provider
+Settings is unavailable on the forwarded URL. Never commit your workspace
+`.env`. [SECURITY.md](SECURITY.md) has the threat model.
