/**
 * Bug #2973: /gsd-profile-user --refresh writes dev-preferences.md to the
 * legacy commands/gsd subdirectory, contradicting v1.39.0's skills-only
 * migration claim that "Legacy commands/gsd directory removed
 * (replaced by skills/)".
 *
 * Root cause: the writer at get-shit-done/bin/lib/profile-output.cjs
 * fell back to commands/gsd/dev-preferences.md when no --output was passed.
 * The /gsd-profile-user workflow does not pass --output, so every refresh
 * deterministically re-creates the legacy directory.
 *
 * Fix:
 *   1. profile-output.cjs default targets skills/gsd-dev-preferences/SKILL.md
 *   2. profile-user.md confirmation message references the new path
 *   3. install.js migrates any existing legacy file into the new skill
 *      location during install (no-op if SKILL.md already exists)
 *
 * This test exercises the runtime behavior of the writer (writes to the
 * skills path) and the structural shape of the workflow message. No
 * source-grep on the .cjs body — assertions go against the writer's
 * actual output and the parsed workflow message.
