 *   2. User profile:       ~/.wrongstack/profiles/<name>/prompts/ (writable, source 'user'/'synced')
 *   3. Bundled with build:  <core>/data/prompts/prompts/**  (read-only, source 'builtin')

 * Writes go to the user layer by default (or the project layer when
 * `scope:'project'`). Favoriting/editing a builtin copies it down into the user
 * layer (copy-on-write) so the read-only dataset is never mutated.
