/**
 * Authored-skill tracking.
 *
 * Records skills that the current user has *published* (as opposed to
 * *installed*). Source-origin skills don't appear in `vskill.lock` (only
 * installs do), so without a separate manifest the `vskill outdated`
 * poll silently ignores them — leaving publishers blind to their own
 * downstream version drift (project_vskill_source_origin_update_tracking.md).
 *
 * File: `vskill.authored.json` at project root.
 *
 * Increment 0794 — US-006 / T-006.
