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.

// Integer literals default to i64 regardless of context: an unannotated
|
|
// `x := <int literal>` local stays i64 even inside a function whose return
|
|
// type is a narrower integer (the implicit-return target must not type the
|
|
// body's declarations), and a large literal initializer keeps its value.
|
|
// Also covers destructure decls (`a, b := ...`), which share the same rule.
|
|
// Regression (issue 0111): these locals adopted the enclosing fn's return
|
|
// type (i32/i8), silently wrapping `big := 3000000000` to -1294967296.
