Remove the call to loadAllFileStatSlims() which pre-loads all ZIP central directory entries into memory. For EPUBs with 2000+ chapters (like webnovels), this exhausts the ESP32-C3's ~380KB RAM and causes abort(). The existing loadFileStatSlim() function already handles individual lookups by scanning the central directory per-file when the cache is empty. This is O(n*m) instead of O(n), but prevents memory exhaustion. Fixes #134
