Publish three example workflows (simple, hiresfix, debug) under
example_workflows/ and link them from the README, in preparation for
ComfyUI Manager / Comfy Registry registration. Replace the single
Juggernaut sweep pair with realistic and anime (Illustrious) pairs to
show the wrapper is architecture-level rather than tuned to one style,
and soften the mask-effect wording to reflect that selectivity is a
soft weighting, not a binary gate.
