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.

// A NON-integral float constant (`4.5`) used as an array dimension is a hard
|
|
// error — only an integral float (`4.0`) folds to a count. Clean diagnostic +
|
|
// non-zero exit, NOT a fabricated length.
|
|
//
|
|
// The dimension follows the unified float→int narrowing rule (F0.11 / issue
|
|
// 0095): an integral float folds, a non-integral one is rejected as "not an
|
|
// integer" — the SAME `floatToIntExact` judgement the typed local/field/param/
|
|
// const sites use (the count path is the last of the five sites to unify).
|
|
//
|
|
// Regression (F0.4 attempt 8, Agra ruling): the integral-float rule accepts
|
|
// `4.0` as a dimension but must keep rejecting `4.5` (it is not an integer).
