docs: document Homebrew, conda-forge, and ComfyUI distribution channels

- README: add Homebrew install, conda (conda-forge, in review), and a
  ComfyUI custom-nodes section.
- CLAUDE.md: per-channel release/bump cadence (Homebrew formula, conda-forge
  autotick bot, ComfyUI Registry); note pip_check: false on the conda recipe.
- Add packaging/conda/recipe.yaml (v1, noarch core-only), verified green on
  conda-forge/staged-recipes PR #33674.

 ## Installation
 
+### Homebrew (macOS / Linux)
+
+```bash
+brew install wiltodelta/tap/remove-ai-watermarks
+```
+
+This installs the core command surface (`identify`, `metadata`, `visible`,
+`erase`) as a self-contained CLI. The diffusion-based `invisible` / `all`
+pipeline needs heavy ML dependencies (torch, diffusers, multi-GB) and is kept
+out of the Homebrew build; add it with the `gpu` extra via pip if you need it:
+
+```bash
+pip install "remove-ai-watermarks[gpu]"
+```
+
+### conda
+
+A conda-forge recipe is under review
+([staged-recipes PR](https://github.com/conda-forge/staged-recipes/pull/33674)).
+Once it merges, the core package installs with:
+
+```bash
+conda install -c conda-forge remove-ai-watermarks
+```
+
+Like the Homebrew build, this is the core command surface; add the diffusion
+`invisible` / `all` pipeline with the pip `gpu` extra.
+
 ### Recommended
 
 Install as an isolated CLI tool — no need to manage virtual environments:

+## ComfyUI
+
+Custom nodes are available so the watermark tools run inside a ComfyUI graph:
+[ComfyUI-remove-ai-watermarks](https://github.com/wiltodelta/ComfyUI-remove-ai-watermarks)
+([registry](https://registry.comfy.org/nodes/remove-ai-watermarks)).
+
+Install via ComfyUI Manager (search "Remove AI Watermarks") or manually:
+
+```bash
+cd ComfyUI/custom_nodes
+git clone https://github.com/wiltodelta/ComfyUI-remove-ai-watermarks
+pip install -r ComfyUI-remove-ai-watermarks/requirements.txt
+```
+
+Nodes: Remove Visible Watermark, Detect Visible Watermark, Erase Region (by
+mask), and Remove Invisible Watermark / SynthID (needs the `gpu` extra).

+  summary: Remove visible and invisible AI watermarks from images
+  description: |
+    Detect and remove visible AI watermarks (Gemini / Nano Banana sparkle,
+    ByteDance Doubao and Jimeng, Samsung Galaxy AI) and strip AI-provenance
+    metadata (C2PA, EXIF, IPTC, PNG text chunks) from images. The core package
+    covers the identify / metadata / visible / erase command surface; optional
+    pip extras add SynthID diffusion removal and additional invisible-watermark
+    detectors.
