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.

// Variadic heterogeneous type packs — generic `$R` with
|
|
// heterogeneous element pick. `foo(..$args) -> $R => args[2]`
|
|
// returns the THIRD arg's value; the ret type is inferred from
|
|
// the third arg's concrete type per call shape.
|
|
//
|
|
// foo(42, 3.2, "hello") → returns "hello" (string).
|

|
|
// Exercises:
|
|
// - generic `$R` inference for non-zeroth pack indices.
|
|
// - heterogeneous mixed-type call args binding into distinct
|
|
// types per position (i64, f64, string).
|
|
// - `pack_arg_types` type-only binding for `inferExprType`
|
|
// pre-mono-scope: without it, the synthesized-ident detour
|
|
// loses the type because the scope isn't set up yet during
|
|
// return-type inference.
