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.

// Inline `xx` cast as the first argument to a struct static method must
|
|
// flow the leading param's type into the cast — otherwise an `xx ptr`
|
|
// targeting a protocol param falls back to i64 and the call frame is
|
|
// corrupted, SIGTRAPping when the body dispatches through the field.
|
|
//
|
|
// Three call shapes that must all succeed:
|
|
// 1. Named-variable receiver: `a : Allocator = xx p; T.init(a, ...)`
|
|
// 2. Free function with inline xx: `make_t(xx p, ...)`
|
|
// 3. Static method with inline xx: `T.init(xx p, ...)` ← used to crash
