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 generic value-param arg that does not fit the param's declared integer type
|
|
// is a hard error even when that type is reached through a type ALIAS
|
|
// (`$K: Count` where `Count :: u32`, `$K: Small` where `Small :: i8`) — a clean
|
|
// diagnostic + non-zero exit, NOT a silent truncating bind.
|
|
//
|
|
// Regression (issue 0083): the value-param range gate matched only BUILTIN
|
|
// constraint names, so an aliased constraint slipped past `intTypeRange` and
|
|
// `Box(5_000_000_000)` with `$K: Count` compiled and bound a truncated value.
|
|
// The constraint now resolves to its underlying builtin (`Count` → u32,
|
|
// `Small` → i8) before range-checking, so an aliased integer constraint behaves
|
|
// exactly like the builtin it names — at both the struct and type-fn binders.
