Merge origin/main into german/navara

Main's work since the last merge runs on the globe contract where this
branch draws through it:

- Satellites take main's classes, sensors, ground-track bearings and
  world time through contract points and rings; launches take the world
  timeline. The satellite's cockpit subject dims, copies positions and
  refocuses through the contract.
- Flights, military and vessels keep main's photos, retry cool-downs,
  world-clock motion and the ship bridge. Trail seeding in the shared
  aircraft tracking reads each layer's clock.
- Traffic's flow lines and single build draw as ground sets; transit
  keeps dated credits and the new cities; CCTV opens the nearest camera,
  and the Quebec overlay projects and tests the horizon through the
  contract. Bikeshare's manager cleanup moved into its current lifecycle.
- Draw keeps main's mark actions across engine switches.
- The world clock in src/time is plain numbers again: Julian dates come
  from src/geo, the frame loop is injected, and the binding to Cesium's
  viewer clock lives in src/globe/cesium/worldTime.js. Navara's sky and
  sun follow the world time; live feeds keep the real time.
- The cockpit's orbital view, with its sensor zoom, ground focus and
  satellite switching, stays Cesium-only for now: Navara hides its entry.
  Its Cesium calls live in src/globe/cesium/orbital.js. The ship bridge's
  finest-detail waterline sampling is Cesium-only too; Navara samples
  loaded geometry and detailed terrain. Both are in KNOWN-ISSUES.
- Main's tests that built a Cesium scene by hand run on the fake engine.
- The boundary manifest is regenerated, the coupling baseline records
  the orbital and bridge code, and the main-chunk baseline is raised to
  the merged size: main itself grew its main chunk by 93,959 bytes
  (gzip -9) since the previous merge base.
