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.7 — full instance state round-trip on a sx-defined
|
|
// `#objc_class`. The plan's first integration smoke test
|
|
// (A.2/A.3/A.4 integration through the now-open dispatch gate).
|
|
//
|
|
// What this exercises end-to-end:
|
|
// 1. `SxFoo.alloc()` — sx-side call lowers to objc_msgSend(SxFoo, sel_alloc).
|
|
// The runtime invokes the synthesized +alloc IMP (M1.2 A.5)
|
|
// which allocates an instance + state struct and binds them
|
|
// via __sx_state.
|
|
// 2. `f.bump()` — sx-side method call lowers to
|
|
// objc_msgSend(f, sel_bump). Runtime dispatches to the IMP
|
|
// trampoline (M1.2 A.4b.ii) which reads __sx_state to find
|
|
// the state pointer and forwards to the sx body
|
|
// `SxFoo.bump(__sx_default_context, state)`. Body mutates
|
|
// self.counter (M1.2 A.3).
|
|
// 3. Repeat to confirm the state persists across calls.
|
|
// 4. release — synthesized -dealloc (M1.2 A.6) frees the state
|
|
// and chains to [super dealloc].
