/**
 * Regression test for bug #2808
 *
 * All 85 GSD SKILL.md files declared `name: gsd:<cmd>` (colon), the deprecated
 * form. Claude Code surfaces the `name:` frontmatter field in autocomplete, so
 * users saw `/gsd:add-phase` suggestions instead of the canonical `/gsd-add-phase`.
 *
 * Root cause: skillFrontmatterName() in bin/install.js converted hyphenated
 * skill dir names to colon form (gsd-add-phase → gsd:add-phase) because
 * workflows called Skill(skill="gsd:<cmd>"). That was the original fix for
 * #2643. Since then, workflows have been updated to use hyphen form (#2808).
 *
 * Fix: skillFrontmatterName() now returns the hyphen form unchanged.
 * Workflow Skill() colon calls are updated to hyphen.
 *
 * This test verifies:
 * 1. skillFrontmatterName returns hyphen form (not colon).
 * 2. Installed SKILL.md would emit name: gsd-<cmd> (not gsd:<cmd>).
 * 3. No workflow contains a Skill(skill="gsd:<cmd>") colon call.
