//! Socket-only session for local development.
//!
//! [`DevSession`] is a parallel entry point to [`super::session::Session`] that
//! starts the same TCP server (same protocol, same `Handler`) but skips
//! PlugInKit / `Info.plist` discovery and the `mount(8)` orchestration done by
//! [`super::mounter::Mounter`]. This lets a `Filesystem` impl be exercised over
//! the wire (e.g. with a separate FSKitBridge / test client) without requiring
//! a registered FSKit appex on the host.
//!
//! Added in subtext's vendored copy; not part of upstream `fskit-rs 0.2.0`.
