Module import_format 

Canonical formatting of a module’s Import statements — the pit-of-success default so import blocks never need manual bikeshedding.

This is a separate pass from source_format, applied by largo fmt, so the formatter’s token-stream invariant is untouched: reordering imports is semantics-preserving (import order never matters), but it does change the token stream, so it can’t live inside format_source.

Only explicit Import … statement lines in the abstract are touched (literate [Alias](uri) links are left as the author wrote them). The block is sorted, de-duplicated, and collapsed to the position of the first import.

Functions

normalize_imports

Rewrite the entry’s abstract Import statements into a single canonical block: sorted, de-duplicated, placed where the first import was, with the rest removed. Prose and code are untouched. Idempotent.
