Surface rename of the signed integer family: s1..s64 become i1..i64
(u1..u64, usize, isize unchanged). 'string' keeps the s-prefix arm in
name classification; width parsing moves to the i-prefix arm next to
isize.
Internal TypeId tags follow the surface (.s8/.s16/.s32/.s64 ->
.i8/.i16/.i32/.i64), as do mono-key mangle fragments (ptr_i64,
tu_i64_bool) and all display/diagnostic formatting (i{d}).
Migrated in the same sweep: stdlib + examples + issue repros + FFI C
companions (shared symbol names like ffi_id_i64), expected
stdout/stderr/ir snapshots, specs.md, readme.md, CLAUDE.md/AGENTS.md,
implementation_plan.md, docs/, issue writeups. Vendored stb_image and
historical flow state left untouched.
zig build test: 426/426; examples suite: 595/595.

// E6b-R — own-wins-over-flat at the NEW use surfaces route-all funnels through the
|
|
// source-aware engine. `main` flat-imports `dep.sx` (which authors `Box { a }`) AND
|
|
// authors its OWN `Box { m }`; the field sets are DISJOINT, so the observable is
|
|
// field access: `.m` typechecks only against main's `Box`, `.a` only against dep's.
|
|
//
|
|
// `WrapU` is authored only by `main`, so its union field type `Box` resolves at
|
|
// registration (`registerUnionDecl` → the source-aware body builder, E6b-R C1) to
|
|
// MAIN's `Box`. Accessing `w.b.m` therefore typechecks, while `dep_box` uses dep's
|
|
// DISTINCT `Box { a }`.
|
|
//
|
|
// Fail-before (pre-E6b-R): `registerUnionDecl` built the union body through the
|
|
// stateless `type_bridge.buildUnionInfo`, whose `findByName` short-circuit bound
|
|
// the global last-wins `Box`. If dep's `Box { a }` won the slot, `WrapU.b` was
|
|
// dep's `Box` and `w.b.m` was a hard "field not found" — silently wrong nominal.
|
|
// Pass-after: the union field is main's own `Box`, `w.b.m` resolves, exit 0.
