Victor Kuznetsov e4f558dccf Add per-region high-resolution text protection (regenerate crisp, scrub everywhere) (#31) ...

Replace the default text-protection path. Differential Diffusion froze text in
latent space, which left SynthID intact inside text (violating remove-everywhere)
and still softened sub-8px strokes (VAE latent limit). _run_region_hires instead
scrubs the whole image, then re-scrubs each detected text block at high resolution
and feather-composites it back: every pixel is regenerated (watermark removed
everywhere) while small text stays crisp (high-res strokes span >1 latent cell).

merge_text_regions + feather_paste are pure and unit-tested; each re-scrubbed
patch is phase-correlated back to the original crop to null the ~1-2px round-trip
offset. Synthetic 18px multilingual text: text-region SSIM 0.28 -> 0.48, visually
garbled -> readable across Latin/Cyrillic/CJK. Legacy _run_differential /
build_change_map remain but are no longer the default. Prod use still requires
confirming via the SynthID oracle that re-scrubbed text zones read watermark-free.
