+Final implementation:
+
+`#[metadata]` registers a `Description` for each entry, and `gen_program!()` collects them. During completion, when a subcommand suggestion is generated, its owning entry's `Description` is resolved via the node path and attached as the suggestion's description text.

+use mingling::{
+    ShellContext, Suggest,
+    macros::{command, completion, gen_program, metadata, suggest},
+    metadata::Description,
