polyc-tui 2026.9.0

//! polychrome operator cockpit — library entrypoint.
//!
//! The cockpit ships two ways: as the standalone `pc-tui` binary (see
//! `main.rs`) and embedded in the `polychrome` operator CLI, which calls
//! [`run`] when invoked with no subcommand (or `polychrome tui`). Both paths
//! go through [`run`]; the binary only adds the `color-eyre` install.
