Module session_manager 

Peer session lifecycle management with per-peer caps, state machine, and idle eviction.

This module provides PeerSessionManager, which tracks active sessions per peer, manages session lifecycle state transitions, enforces per-peer session caps, and applies global idle timeouts based on logical tick counts rather than wall-clock time.

Session Lifecycle

Initiated → Established → Closing → Closed
    ↓                        ↑
    └────────────────────────┘  (idle eviction marks Closed directly)

Example

use ipfrs_network::session_manager::{
    PeerSessionManager, SessionManagerConfig, SessionDirection,
};

let config = SessionManagerConfig::default();
let mut mgr = PeerSessionManager::new(config);

let sid = mgr
    .open_session("peer-alpha", SessionDirection::Inbound, 0)
    .expect("open session");

assert!(mgr.get_session(sid).is_some());
