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 across every control-flow / capture / binding form,
|
|
// plus bare later uses. A reserved type-name spelling (`i2`, `u8`, …) works as a
|
|
// binding name in a destructure, an `if`/`while` optional binding, a `for`
|
|
// capture + index, and a match-arm capture; a backtick-named function is
|
|
// bare-callable; and a backtick struct field is bare- or backtick-accessible.
|
|
// The escape is needed only at the binding site — a later BARE reference / call
|
|
// / member access resolves to the binding. A *bare* binding name is still the
|
|
// reserved type (see examples/1121), so the escape is the only way to spell
|
|
// these as values.
|
|
// Regression (issue 0089 — attempt-2 completeness across binding forms).
