TASK 21 slice 3: loop control in MediaVideoSource (process factory + Loop flag)

- IMediaFrameSource gains bool Looping.
- MediaVideoSource ctor takes Func<IDecodeProcess> processFactory instead of a
  single IDecodeProcess: a System.Diagnostics.Process can't be re-Start()ed, so
  each loop pass creates a fresh decoder. Decode wrapped in do-while(Looping):
  restart on natural EOF instead of raising Completed.
- Production wiring (MainViewModel media factory): passes the process factory
  AND FfmpegFrameRateProbe -- closes the slice-2b gap where production had no
  probe and therefore no pacing.
- Tests: loop test (single frame re-emits across passes, Completed only when
  loop cleared); fakes updated for the new interface member. Media tests 12/12,
  build 0 warnings.

Wiring Source.MediaIsLooping into the flag needs a manager-level per-path loop
provider -> lands with the UI-picker (acquisition) slice.

Derivative reference: looping media by restarting decode on EOF, standard in
playback/overlay tooling (OBS media source repeat).

TASK 21 slice 1 step 3: IMediaFrameSource + MediaVideoSourceManager

Refactor MediaVideoSource onto IMediaFrameSource (Key/FrameAvailable/Completed/
StartAsync/StopAsync, renaming Start->StartAsync, FrameReady->FrameAvailable),
behavior preserved. Add MediaVideoSourceManager: app-wide decode-session owner
refcounted by MediaPath with Func<string,IMediaFrameSource?> factory seam,
Acquire/Release/ReleaseAll/GetLatestFrame, coalescing each file's frames onto
the UI dispatcher onto one shared WriteableBitmap; MediaFailed + PreviewBitmapChanged.

Mirrors ScreenCaptureManager (screen-capture session ownership + dispatcher
coalescing), per the codebase precedent and derivative-work rule.

Tests: MediaVideoSourceManagerTests (5 unit + 1 integration: single shared
bitmap, coalesce-to-latest); MediaVideoSourceTests updated for renames.
10/10 media tests pass, build 0 warnings. Docs (TASKS/HANDOFF/ai.md) updated.
