Session hard timeout — 0 means unlimited (Issue #33). Configurable via session_timeout_secs in server.json. PFS ratchet already handles key rotation, so forced session expiration is unnecessary and causes reconnect failures.

IDLE_TIMEOUT

Session idle timeout (default)

MAX_SESSIONS

Maximum sessions on 1GB VPS

TAG_WINDOW_SIZE

Tag window size (allow out-of-order packets)
