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.

// Backtick raw identifier in TYPE position (the universal model, issue 0089):
|
|
// `` `name `` is the LITERAL identifier `name` used as a type reference, never
|
|
// the builtin/reserved spelling. A reserved type spelling (`i2`, `u8`, …) can
|
|
// therefore both DECLARE a type (struct / enum / union / error-set / alias) and
|
|
// be REFERENCED as that type via the backtick — while a BARE `i2` in type
|
|
// position remains the signed-int type (see `add` below) and a bare reserved-
|
|
// name declaration still errors (see examples/1141). The backtick is required
