Adds a guide-type CLI Tools entry for OpenDesign, the open-sourced
claude.ai/design skills pack. It has no standalone config - it inherits
the host agent's model/provider config - so once the host (Claude Code,
Cursor, Codex, Gemini CLI, OpenCode) points at 9Router, /opendesign
sessions route through automatically.
isPathLike rejected any line with a colon, so Windows absolute paths
(C:\Users\me\a.js) were never recognized and find dumps went uncompacted.
find.js also split only on "/", mis-grouping backslash paths.
- autodetect: treat drive-letter prefix (X:\ or X:/) as path-like before
the general colon rejection.
- find.js: split on the last "/" or "\" separator and normalize emitted
directory labels to forward slashes.
