fix(robocasa): editable install + switch to lerobot/smolvla_robocasa

- pip install from git omits data files like box_links_assets.json
  (not declared in package_data). Clone and install editable so the
  source tree is used at runtime.
- Download only tex + fixtures_lw asset types (smoke test doesn't need
  objaverse/aigen objects). Pipe 'y' to auto-accept download prompt.
- Switch CI policy from pepijn223/smolvla_robocasa to lerobot/smolvla_robocasa.
