Settle the draw decisions in the renderer contract

- lodGroup links items across sets as one thing at different detail;
  picks name the member shown and report the group. displayRange is
  half-open.
- An orbits capability: the renderer propagates two-line elements with
  SGP4 on the set's motion clock. The stub propagates with satellite.js.
- Height queries see draw sets only with includeInHeightQueries (was
  excludeFromHeightQueries); HeightSample.source gains 'set'.
- courseGlide is a capability; courseBlendMs eases the course on every
  renderer.
- Arc segments climb at climbMps; a negative minDtS stays for the
  aircraft warm-up.
- The star catalogue is optional, a hidden column row keeps its motion,
  and draw.clampState() reports the drape fallback.

Checks cover the climb and warm-up, lodGroup ranges, orbits against SGP4
(with and without motionSegments), hidden rows resuming, and sets not
answering height queries by default.
