Apply Blur Operator for masked face blur in VSE.

Bake-and-swap blur operators for VSE.

Provides operators to apply blur effects using mask strips

generated by the face detection operators.

This module bakes masked blur into a regular video file using the inference

server, then swaps the active strip's source filepath to the baked result.
