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.

// E6a — per-decl nominal identity for UNION decls. A bare UNION reference is
|
|
// non-transitive AND ambiguity-checked at every site, exactly like the enum
|
|
// (0795) and struct (0767) forms. `main` flat-imports two modules that each author
|
|
// a same-name `Pair` union and authors none itself, so EACH of the following bare
|
|
// UNION forms is a genuine collision the source cannot disambiguate — and each must
|
|
// emit the LOUD "type 'Pair' is ambiguous" diagnostic and poison the result, NEVER
|
|
// silently pick a global `findByName` last-wins author:
|
|
//
|
|
// - reflection / type-arg slot `size_of(Pair)`
|
|
// - typed annotation `u : Pair = ---`
|
|
// - type-as-value `t : Type = Pair`
|
|
// - type-category match arm `case Pair:`
|
|
//
|
|
// Fail-before (pre-E6a): the stateless `type_bridge.resolveInlineUnion`
|
|
// `findByName` short-circuit interned ONE global last-wins `Pair`, so every bare
|
|
// form silently resolved to it and the program exited 0.
