docs: add FLUX.2 and Qwen-Image to credits

fix: remove Z-Image from img2img/inpaint — crashes on Colab, generation only

fix: zero-exception error handling — no traceback, just clean print

fix: no-traceback error messages — just clean printed warnings with instructions

fix: clean notebook with friendly error for missing model selection

Update FreeFakeStudio.ipynb

feat: add Z-Image to img2img/inpaint, set Qwen-Image-Edit as default

fix: bump clothing denoise to 0.75 — 0.55 was too conservative

Update readme.md

fix: per-edit-type denoise — background=1.0 (full regen), clothing=0.55 (preserve shape)

fix: clothing-only mask for non-background edits — no more green dresses in background

fix: FLUX img2img always routes through inpaint with smart mask selection

fix: prompt-aware img2img — only mask background when prompt is about background

fix: use denoise=1.0 for img2img background — eliminates original color bleed

fix: cap steps at 8 for distilled FLUX Klein — 20 steps degrades quality
