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.

// `raise` rejections (ERR step E1.3):
|
|
// - `raise` is only valid inside a failable function,
|
|
// - a literal `raise error.X` must name a tag in the function's set,
|
|
// - a variable `raise e` must carry a set that is a subset of the
|
|
// function's set.
|
|
// The positive case lives in `examples/219-raise.sx`. Parse-time rejections
|
|
// (`raise` in expression position / inside `defer` / `onfail`) are covered by
|
|
// the inline parser tests.
