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 — follow-up #2 (generic $R
|
|
// return type).
|
|
//
|
|
// A pack-fn's return type can be a generic name (`$R`) — bound at
|
|
// the call site to match the body's natural type or the caller's
|
|
// target. Today's `monomorphizePackFn` calls `resolveReturnType`
|
|
// which treats `$R` as an opaque struct, so the mono's signature
|
|
// gets a wrong ret_ty and the value is silently zero / garbage.
|
|
//
|
|
// `first(42)` should return 42; the lock-in pins today's `0`.
|
|
// Next commit infers the ret type from the body's tail expression
|
|
// (or first `return X;`) and rebuilds the mono signature.
