Summary

• Add a backward-compatible persist_between_minigames property to every visual-effect template.
• When enabled, camera transforms, flips, zoom, overlays, pixelation, and HSL/Sepia requests detect an active-camera change and rebind to the new camera.
• Old camera state is removed before the new camera is attached, preventing stale transforms and duplicate overlays.
• Missing properties default to false; playback stop/pause still calls StopAllEffects and clears persistent runners.
• Document the new property for all effects.

Validation

• Built against the installed Bits & Bops game assemblies.
• Build result: 0 warnings, 0 errors.
• git diff --check passes.

Closes #34.

Looks good, just the name of the param is too long, replace everywhere with shorter variant
