The issue-0076 reserved-type-name binding diagnostic only ran over main-file decls, so an imported module (or the stdlib) could still declare `s2 := ...` and reach lowering, where the address-of family loads the whole aggregate and passes it by value to a `ptr` param — LLVM verifier abort. Extend coverage to every compiled module: a dedicated `checkBindingNames` walk (in semantic_diagnostics.zig) visits every var/`:=`/typed-local binding name and function/lambda/struct-method parameter at any depth, with NO main-file filter, descending the `namespace_decl` that a `mod :: #import` wraps so imported-module decls are reached. It tracks each module's source_file (save/restore per node) so the diagnostic renders against the imported module's text. Rejection still defers to the parser's `Type.fromName` classifier; the unknown-type check (0064) stays main-file-only. No lowering special-case; `.identifier`-only address-of paths are unchanged. Stdlib audit: the only reserved-name bindings under library/ were two `u1` locals in ui/renderer.sx (UV coords) — renamed to u_min/u_max/v_min/v_max. Regression test: examples/1120-diagnostics-imported-reserved-type-name.sx (+ companion mod.sx) — an imported `s2 := ...` now emits the clean diagnostic at the import's declaration site (exit 1), not an LLVM abort. Resolves issues 0076 (coverage extension) and 0077.

// A value binding spelled as a reserved type name (`s2`, the `sN` arbitrary-

// width int syntax) is rejected at its declaration site even when it lives in
|
|
// an IMPORTED module — the reserved-name binding diagnostic covers every
|
|
// compiled module, not just the main file. Without universal coverage the
|
|
// binding reaches lowering and aborts LLVM verification (a loaded aggregate
