Module session_backend 

Pluggable session storage backend.

Built-in backends:

• BinaryFileBackend — compact binary file (default).
• StringSessionBackend — portable base64 string (env vars, Docker, CI).
• SqliteBackend — SQLite (sqlite-session feature).
• InMemoryBackend — ephemeral, for tests / fresh-start bots.
