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.
