Alexander KharinandClaude Fable 5 d77af07189 Apply workflow improvements: runnable defaults, templates, dep trim, CI 
- Bundle example inputs (example_inputs/: pinhole + fisheye JPEG, example
  trajectory .npy); install.py copies them into ComfyUI's input/ folder and
  every LoadImage/LoadTrajectory default now points at them, so the shipped
  workflows queue on a fresh install.
- Template browser: add same-name .jpg thumbnails for 10 workflows
  (workflows/ is already a recognized template dir); drop the stray
  workflows/__init__.py.
- Move superseded reference graphs to workflows/legacy/ (SD-checkpoint
  outpaint variant, manual multi-view fisheye depth) - out of the template
  browser, still documented.
- video_camera.json: remove dead-end BlurMaskFast (radius 0/0 no-op),
  easy-mathInt pad math and dangling VHS_VideoInfo; swap KJNodes
  GetImageRangeFromBatch for built-in ImageFromBatch. Pack deps cut from
  five to two (VideoHelperSuite + Florence2).
- New workflows/record_trajectory.json - produces the .npy trajectory that
  PC_enricher and wan_vace_ref_to_video consume.
- Stamp extra.camera_comfyui_rev=1 in all workflows for future migrations;
  prune 8 pre-existing stale link references found by a bidirectional
  integrity sweep.
- CI: .github/workflows/validate.yml runs the schema validator,
  installer-logic tests and 4D smoke suite (CPU torch) on PRs and main.
- README + docs/workflows_review.md updated accordingly.
