trusty-mpm 1.3.4

//! `tm` / `trusty-mpm` — unified MPM CLI entry point.
//!
//! Why: this file is intentionally thin. All logic is in the submodules below;
//! `main` only parses arguments, sets up tracing for long-running modes, and
//! dispatches to the appropriate handler function.
//! What: module declarations, lazy HELP initializer, `main()` with clap
//! dispatch.
//! Test: `cargo test -p trusty-mpm` runs the full suite in `tests.rs`.

/// inside the dispatcher — specifically so `tm projects <verb>` and a
/// non-interactive bare `tm projects` both flow through the completely
/// unmodified clap definition: the latter must keep failing with a clap usage
/// error (exit code 2), unchanged from the pre-#2118 behavior. (The EXACT

/// invariant this interception actually depends on, and the one that IS
/// stable, is the non-zero exit code.) "Interactive" requires BOTH stdin and
/// stdout to be real terminals (`commands::projects::should_launch_bare_tui`)
/// — stdout alone is not enough: a supervisor/wrapper that redirects stdin
/// from `/dev/null` while leaving stdout attached to a pty would otherwise
/// launch a raw-mode TUI with no keyboard path able to exit it. See
