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.

// Pre-fix: `resolveType(null)` silently returned `.i64`, so a top-level
|
|
// var without a type annotation got typed as `i64` regardless of what
|
|
// the initializer was. For `g_pi := 3.14;` this meant the float literal
|
|
// was assigned to an i64 slot, producing a wrong value at runtime or
|
|
// the wrong codegen shape.
|
|
//
|
|
// After the fix `lowerVarDecl` at the top level mirrors the local-scope
|
|
// path: explicit annotation → resolveType; no annotation → infer from
|
|
// the initializer's type. Mirrors how `:=` already worked for locals.
