`ail describe <Type>.<op>` is the canonical form (model 0007 §1) but
currently errors `no module \`Series\` in workspace` because
resolve_describe_name (crates/ail/src/main.rs) only looks up the left
segment as a MODULE, never as a known TYPE. The module-scoped
`series.push` and bare `push` forms already resolve fine.
RED pin: describe_resolves_type_scoped_op asserts
`ail describe --workspace examples/series_sma.ail Series.push` exits 0
and prints the `series.push` def. Fails today on the exit-0 assertion
(feature absent), not on scaffolding. GREEN side follows.
