📝 Walkthrough

Walkthrough

The AST scanner now removes aliases whose bases are not imported, recalculates import-block boundaries, and recognizes address-of-wrapped import chains. Tests cover alias resolution, import classification, sorting, re-export placement, and idempotence.

Changes

Import scanning and sorting

Layer / File(s)	Summary
Alias resolution and block boundaries src/ast_scan.zig, src/ast_scan_test.zig	Import records alias resolution state. Unresolved aliases are removed, and import-block boundaries are recalculated. Tests verify these cases.
Address-of import classification src/ast_scan.zig, src/ast_scan_test.zig	Import and declaration scanning unwraps & expressions. Tests distinguish address-of import chains from local identifiers.
Sorting and re-export validation src/zsort_test.zig	Tests cover resolved aliases, local-module re-exports, address-of import ordering, --bottom behavior, and stable multi-entry re-export blocks.

Estimated code review effort: 3 (Moderate) | ~20 minutes
