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 generic value-param arg that does not fit the param's declared integer type
|
|
// (`Box(5_000_000_000)` for `$K: u32`) is a hard error — a clean diagnostic +
|
|
// non-zero exit, NOT a silent truncating bind.
|
|
//
|
|
// Regression (F0.4 attempt 8, item 1): `resolveValueParamArg` bound the folded
|
|
// i64 without range-checking the declared type, so an out-of-u32 arg compiled
|
|
// and ran. The bind now routes a `u32` count through the shared
|
|
// `program_index.foldDimU32` gate (the same one array dims / Vector lanes use),
|
|
// so an oversized value is rejected before instantiation.
