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.

// M1.2 A.4b.i — '__sx_state' ivar registration on sx-defined
|
|
// '#objc_class'.
|
|
//
|
|
// Class-pair init now:
|
|
// 1. allocs the class pair
|
|
// 2. registers a single '__sx_state : *void' ivar
|
|
// 3. finalises the class
|
|
// 4. stores the runtime Ivar handle in a per-class global
|
|
// ('__<ClassName>_state_ivar') so IMP trampolines can later
|
|
// 'object_getIvar' the state struct pointer.
|
|
//
|
|
// Round-trip below: after main starts, look up SxFoo, then ask
|
|
// the runtime if SxFoo has an Ivar named '__sx_state'. Returns
|
|
// non-null iff registration succeeded.
|
|
//
|
|
// IMP trampolines (A.4b.ii) and the '+alloc' / '-dealloc'
|
|
// overrides (A.5 / A.6) come next.
