//! Per-session command dispatcher — where every Pack, schema, search,
//! diagnostics and dependency operation actually runs.
//!
//! Each [`Session`] spawns one task running [`background_loop`]. The loop
//! pulls `(reply_sender, Command)` pairs off the session's mpsc channel,
//! handles the command synchronously against the session's in-memory state
//! (open packs, dependency cache, settings cache, schema), and ships every
//! response back over the per-request `reply_sender`.
//!
//! Running commands serially per session is what keeps state consistent
//! across many concurrent requests in the same session: a `SavePack`
//! followed by a `ClosePack` always sees the right Pack, even when the
//! WebSocket multiplexer is firing requests as fast as the client sends
//! them.
//!
//! Telemetry: each dispatched command is recorded via
//! [`rpfm_telemetry::record_action`] so usage counters reflect what the
//! session actually did.
