Release 0.25.0

Breaking, on top of the released 0.24.0.

Removed from the CLI: --model, --steps, --guidance-scale, --device, and the
deprecated --auto. Removed from InvisibleEngine and WatermarkRemover: the
model_id, num_inference_steps and guidance_scale parameters, remove_watermark_batch,
and the remover's region/region_feather path. Each pinned a value the two
remaining profiles fix -- the model stack, the per-stage distilled schedule,
CFG 1.0, CUDA -- so their only outcome was an error raised several frames below
the caller.

Also removed: the public remove_ai_watermarks.upscaler module, the
--min-resolution and --upscaler options and the published esrgan extra (0.24.0
shipped them unreachable); the pytorch-xpu index; and "diffusion" from the "all"
extra, which qwen-zimage already pulls.

Behaviour changes a caller can see:
- invisible-watermark removal now requires the qwen-zimage extra, not diffusion.
  Both profiles run the DiffSynth Z-Image face stage, so a torch+diffusers-only
  environment used to pass the availability gate and then die there. Every
  install hint names qwen-zimage now.
- get_device() answers cuda or cpu only, and the CUDA-only refusal names the
  resolved device rather than the raw argument.
- adaptive_polish is tri-state. Unset follows the profile (off for qwen-zimage,
  on for sdxl-zimage) and is resolved inside the engine, so a library caller and
  a CLI caller on one profile now produce the same pixels; they did not before.

ComfyUI node 0.1.15 is already published and tracks this surface.

pre-commit: 1) maintain.sh - exit 0 (1093 tests, Pyright 0 errors, no
vulnerabilities); 2) /simplify - n/a, version bump only; 3) docs sync - version
appears in pyproject.toml, __init__.py and uv.lock, all three updated; 4)
CLAUDE.md - no rule change
