A check skipped because a flight or a playing Director scene was in
progress used to be dropped, so a run that ended or held on a stars-only
shot stayed there until the next camera move. Keep watching instead:
the settle check retries once the flight or scene ends, within its
existing five-minute bound, and a moveEnd that arrives while it is
deferred keeps the check armed rather than stopping it.
Also test that the free-look limit never raises Cesium's trackball
height and that dispose keeps a value set after install, note in its
JSDoc the enableLook case it cannot tell apart, and document the
trackball change and the retry in CURRENT-STATE and the changelog.
