Cursor installs both a skills and a commands surface and shows both in '/', duplicating every /gsd-*. Extend the #789 CodeBuddy de-dup to Cursor: convertClaudeCommandToCursorSkill (in both src and the live bin/install.js) now emits user-invocable:false, so the skill stays model-invocable while the commands surface is the single '/' entry point.
Closes#2341. Admin-merged (self-review bypass) with full green CI.
