/**
 * skills/store.ts
 *
 * Storage seam for the skill model. The store is an injectable interface so the
 * `SkillService` (service.ts) has no direct filesystem or transport dependency
 *, a consumer can back it with a directory of Markdown files (the bundled
 * `FileSystemSkillStore` below), an in-memory map for tests, or a remote store,
 * without the service or the gateway verbs changing. This is the same
 * injectable-I/O shape the push and subscription stores follow.
 *
 * The filesystem store is the canonical on-disk form: one `<name>.md` document
 * per skill in a single directory, which is exactly the Markdown-plus-
 * frontmatter shape `model.ts` reads and writes. `delete` means delete, the
 * file is removed, not tombstoned.
