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-name MEMBER positions are EXEMPT from the reserved-type-name rule:
|
|
// a bare reserved spelling (`i2`, `u8`, `i1`, …) is legal as a struct FIELD
|
|
// name, a union TAG name, and a protocol METHOD-SIGNATURE name. These are
|
|
// unambiguous — the name sits in a member slot and is reached via `obj.name`
|
|
// (or dispatched by string), so it is never type-classified and never
|
|
// mislowers. The backtick form is optional there and resolves to the same
|
|
// member. Backtick access (`obj.`i2`) and bare access (`obj.i2`) both work.
|
|
//
|
|
// The exemption stops at member SIGNATURES: an `impl` method DEFINITION is a
|
|
// real function, so its name is a declaration site (like a free function) and a
|
|
// reserved spelling still needs the backtick (`` `i2 :: (self) ``) — bare would
|
|
// be type-classified and mislower (the issue-0076 protection). A bare reserved
|
|
// VALUE binding / declaration name still errors (see examples/1119, 1141, 1142).
|
|
// Regression (issue 0089 — attempt-7: pins the Agra-ruled member-name exemption).
