fix(camera): leave flights and scenes to their framing

Review follow-ups for the globe-in-view recovery and voice limits.

- Leave a camera flight in progress and a playing Director scene, holds
  included, to their own framing. The recovery is now installed with the
  scene tools, which own the Director, and reads its running state.
- Reuse a voice turn's half-degree proof only from the position and
  direction it was proven at, so a release that moves the camera checks
  the turn again.
- Share one free-globe-camera check between the recovery, the voice
  turn limit and the globe rotation.
- Keep an enableLook setting other code makes after the free-look limit
  is installed, instead of writing back the install-time value.
- Name the nudging test for what it asserts, the 1% floor, and document
  that a view losing its surface without a camera move waits for the
  next one.
