trusty-mpm 0.19.2

//! Managed session-manager methods for [`DaemonClient`].
//!
//! Why: the `/api/v1/sessions/managed/*` route family is the convergence target
//! for every managed-session UI — the `tm` CLI today, STUI (#1272) and TELUI
//! (#1433) next. Before this module each surface hand-rolled `reqwest` calls and
//! ad-hoc response structs; gathering them as typed [`DaemonClient`] methods wires
//! each endpoint exactly once. They live in a sibling file (not `mod.rs`) so the
//! 463-SLOC client `mod.rs` stays under the 500-SLOC cap; this file can reach the
//! `base`/`http` fields because they are `pub(in crate::client::http_client)`.
//! What: one async method per managed endpoint, each building the URL from
//! [`DaemonClient::base`], sending via the shared `reqwest::Client`, checking the
//! status, and deserializing the typed wire DTO from `super::types`.
//! Test: `cargo test -p trusty-mpm` (`managed_*` round-trip tests in `tests.rs`)
//! covers wire-shape deserialization; live HTTP is exercised by the daemon's
//! `tests/session_manager_mvp.rs` integration suite.
