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.

// Large (64KB+) stack arrays compile and are accessed in place: `---`

// emits no initializer store, and element reads GEP the array's storage

// instead of loading the whole array as a value.
|
|
//
|
|
// Regression (issue 0124): both whole-aggregate shapes — the undef
|
|
// store from `---` and `index_get` on the loaded array value —
|

// scalarized into one SelectionDAG node per element and segfaulted

// `sx build` at [65536]u8.

// Results print via out/int_to_string: `{}` formatting would pull the
