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.

// Entry-point exit-code truncation (ERR step E4.2, non-failable integer main).
|
|
// `main :: () -> T` (integer) exits with the return value truncated to u8 —
|
|
// matching C `main` / the OS exit-status byte, so the JIT (`sx run`) and an AOT
|
|
// binary agree. Here 1105 & 0xFF == 81, so this program exits 81 (NOT 1, which
|
|
// was the old buggy "out of 0..255 range -> failure" behavior).
|
|
//
|
|
// Run: ./zig-out/bin/sx run examples/238-main-exit-truncation.sx ; echo $? # 81
