📝 Walkthrough

Walkthrough

Alias resolution now uses fixed-point iteration to support chained aliases. It removes aliases based on local declarations and cyclic chains. Alias member status remains available. Tests cover resolution, ordering, cycles, import boundaries, and bottom-positioned sorting.

Changes

Alias resolution and sorting

Layer / File(s)	Summary
Fixed-point alias resolution src/ast_scan.zig	Alias resolution now supports multi-hop chains and declaration-order independence. Unresolved aliases based on local declarations or cycles are removed. Alias member status is preserved.
Alias chain regression coverage src/ast_scan_test.zig, src/zsort_test.zig	Tests cover direct aliases, multi-hop chains, declaration order, cyclic aliases, import boundaries, bottom-positioned imports, and idempotent sorting.
