German Khokhlov 7abf74518f Cut duplicated and dead code across the engines, the layers and the QA scripts
- src/geo drops the ported debug argument checks and the tests that
  bitExact already covers; package boundaries accept a directory entry,
  so src/geo/ is listed once per group.
- Cesium no longer carries movers and lines nobody draws with: they are
  optional engine capabilities. The fake engine and the Cesium camera use
  the shared cameraMath; unused contract tables, clock.ticked, the
  'finest' surface detail and Navara click statistics are gone.
- ALPR keeps one overlay core and one presentation model for both
  engines, bikeshare one station bookkeeping, the Navara ground effects
  one definition helper; image atlases, view centres, mover banks and
  colours are shared.
- The legacy switch route, the clock offset and rate controls and other
  unused exports are removed.
- The acceptance runs the Navara draw, geo import and scope checks;
  scenarios use the harness switch and page helpers; the main chunk
  check keeps the size budget only and runs once in CI.

// Contract: a cold start loads only the engine it starts. From the network
// log of a fresh page:
// - a cold Navara start requests nothing of the Cesium library (/cesium/…:
// Cesium.js, its workers and assets);
// - a cold Cesium start requests no chunk that carries three or Navara code
// (the FORBIDDEN_MARKERS of src/tooling/mainChunk.js) and no Navara wasm.
// Control: after a pick to the other engine, its code is requested, so the
// detection sees what it is looking for.
