/**
 * JSON store abstraction for local dataset access.
 *
 * Mirrors PRTS-MCP's `ts/src/data/stores.ts` shape-for-shape so the data
 * layer stays portable across the two projects. Business code only ever
 * touches the {@link JsonStore} interface; whether a file lives in a real
 * directory, inside a zip, or in a bundled fallback is invisible to callers.
 *
 * The same path-safety guarantees are preserved:
 *   - backslashes normalized to forward slashes
 *   - no leading "/"
 *   - no ".." segments
 *   - resolved target must remain inside the store root (DirectoryStore)

     * survives as a string. Use it for any table containing `{id, text}`
     * localization objects.
