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.

// Regression (issue 0059): a function with NO explicit return type infers it
|
|
// from the body, which references the function's own parameters. The inference
|
|
// must see those params — before the fix they weren't in scope during
|
|
// return-type resolution, so the inferred type came out `.unresolved` and tripped
|
|
// the LLVM-emission guard ("unresolved type reached LLVM emission"). Whether it
|
|
// slipped through used to depend on a same-named binding lingering from earlier
|
|
// lowering. Covers the arrow (`=>`) and inferred-via-`return` forms, at top level
|
|
// and as locals.
