Adapts the upstream baoyu-article-illustrator skill (verbatim-copied in
the previous commit) to Hermes' tool ecosystem, matching the pattern
used by baoyu-infographic.
- Metadata: openclaw → hermes; add author, license, tags, category
- Triggering: slash command + CLI flags → natural language
- User config: remove EXTEND.md, first-time-setup, preferences-schema
- User prompts: AskUserQuestion (batched) → clarify (one at a time)
- Image gen: baoyu-imagine → image_generate (describe refs in prompt text)
- Platform: drop Windows/PowerShell; Linux/macOS only
- File ops: switch to write_file / read_file
- Watermark: opt-in per-article instead of EXTEND.md-driven
- Add PORT_NOTES.md describing the adaptation and sync procedure
Style, palette, and prompt/system.md reference files are verbatim copies
and are the sync points with upstream.
