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.

// Backfill for Phase 1D cluster 1.32 (PLAN-FFI.md): `#objc_call(CGRect)`
|
||
// and `#objc_call(u64)` against `class_addMethod`-registered IMPs.
|
||
// Both shapes were already exercised transitively in earlier work —
|
||
// CGRect is structurally a 4×f64 HFA (same as UIEdgeInsets from
|
||
// ffi-objc-call-07), and u64 is i64 at the LLVM level (same as the
|
||
// i64 return from ffi-objc-call-04's `hash`). The cluster-1.32
|
||
// migration of `uikit_keyboard_will_change_frame` was the first
|
||
// place we used both shapes through `#objc_call` directly, but the
|
||
// keyboard-change-frame callback isn't reached by the chess launch
|
||
// path, so this test gives the two shapes their own runtime lockdown.
