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.

// A typed module-level constant whose initializer does not match its
|
|
// annotation is a compile-time type error — not a silently-accepted const.
|
|
// Each declaration below pairs an initializer with an incompatible annotation,
|
|
// so the compiler must emit a `type mismatch` diagnostic at the initializer and
|
|
// abort (exit 1) rather than registering a usable const.
|
|
//
|
|
// Regression (issue 0088): `N : string : 4` was accepted; `print(N)` then
|
|
// segfaulted (an integer emitted as a `string` const → a bogus pointer) and
|
|
// `[N]i64` folded `N` to 4. The fix rejects the declaration at the root. The
|
|
// validation is type-based, so a const-EXPRESSION initializer (`E : string :
|
|
// M + 2`, `V : string : -M`) is rejected just like a literal — not skipped
|
|
// because its node kind isn't a literal (issue 0088, attempt 2).
|
|
//
|
|
// The mixed-numeric pair (`i64 : M + 0.5`, `i64 : 0.5 + M`) is rejected in BOTH
|
|
// operand orders: arithmetic binary-op inference now promotes int+float to the
|
|
// float result (`Lowering.arithResultType`), so an i64 annotation no longer
|
|
// matches a float-producing initializer regardless of which operand is the
|
|
// float (issue 0088, attempt 3 — the inferExprType promotion root fix).
