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.

// Generic function with a value-carrying `!` return composes (ERR E5.1

// sub-feature 8). A `$T: Type` generic whose return is `(T, !E)` monomorphizes
|

// per call: `return try f()` propagates the closure's error, and each
|
|
// monomorphization's success value flows through as the concrete `T`.
|
|
// (Regression: confirms issue 0062 was an invalid-syntax repro — the bug only
|
|
// appeared with the non-generic `T: Type` form; the `$T` form works.)
