Claude a7417b578d Roto Brush: don't run the classic engine silently under a selected model
With SAM 2 (or MobileSAM) chosen, a propagate that started before the model had loaded ran
the whole job on the classic engine and reported nothing. The chosen model is now in use
before a job that segments with it starts (Roto Brush 2.0 / 3.0 and Object Matte):

- roto.propagate and the other Roto jobs wait for a load or download under way when called with
  wait: true (bounded to 10 minutes). Without wait they refuse while the model is still loading,
  and start the load in the background. A model that is not installed, or failed to load, is
  refused either way.
- roto.status reports model {selected, installed, active, loading, error} and a notice while the
  chosen model is not the one in use. source is "model" for a frame the model segmented on its own,
  instead of "classical".
- Auto-propagate keeps edited instances pending while the model loads, and shows errors as toasts
  instead of dropping them.
- Docs: what propagate does now; tracked frames live in the session that ran propagate and are not
  saved in the project file, so a separate render process does not show them; roto.model.select
  lists sam2.1-hiera-tiny.

Tests: a selected model that is not installed refuses to propagate (no weights needed); SAM 2
selected without wait is loaded before propagate (EFFECTCRAFT_SAM2). The SAM 2 tests and the
failing-tracker test take the Roto test lock, since they share the process-wide model slot.
