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.

// FFI large-struct (>16 B) by-value roundtrips. These route through

// the byval-pointer ABI path (caller copies onto its stack, hands the
|
|
// callee a pointer; on AAPCS64 a separate `x8` indirect-return
|
|
// register; on SysV AMD64 a hidden first arg). Distinct from the
|
|
// register-pair / [2 x i64] / HFA paths the small-struct baseline
|
|
// covers — locking those in here keeps the byval path honest.
