/**
 * Read a single value from `localStorage`.
 *
 * Sentinels:
 * - `Item not found: <key>` — key absent (`getItem` returns null)
 * - `Storage unavailable: <reason>` — when the renderer denies access
 *   (e.g., privacy modes, file:// origins under stricter Electron settings)
 *
 * Returns the raw stored string for present keys (which may itself be
 * JSON-encoded — callers parse).
