//! picoem-debug — placeholder crate for the future GDB RSP server,
//! instruction trace, and DWT-driven tooling. Slated for Phase 4+ of the
//! HLD roadmap. Kept in `default-members` so workspace-wide builds prove
//! the manifest still resolves; intentionally has no implementation.
//!
//! When work resumes, the entry point should be a `pub fn` here that
//! `rp2350_emu_tui` / `rp2040_emu_tui` can attach to in their debug builds.

// Phase 4+ scaffolding lands below this line.
