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.

// Reserved/builtin type names are rejected as binding NAMES across every
|
|
// control-flow and destructuring form, not just plain `var`/param decls: a
|
|
// destructure name (`i2`), an `if`/`while` optional binding (`u8`/`i16`), a
|
|
// `for` capture and index name (`bool`/`i32`), and a match-arm capture
|
|
// (`string`). Each spelling parses as a `.type_expr`, so the address-of family
|
|
// in lowering mis-lowers it (a loaded aggregate passed by value to a `ptr`
|
|
// param → LLVM verifier abort). The declaration-site diagnostic comes from one
|
|
// EXHAUSTIVE binding-name walk, so no syntactic binding form can slip through.
|
|
//
|
|
// Regression (issue 0076, attempt-4 coverage). Expected: one error per
|
|
// offending name; exit 1 — NOT an LLVM verifier abort.
