Subject: [PATCH] fix: increase SPIFFS_OBJ_NAME_LEN to 64 for long session
 filenames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #147 — Feishu open_id produces session filenames that exceed the
default 32-byte SPIFFS object name limit, causing "Cannot open session
file" errors.
