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.

// Regression: when a `#jni_call` method returns a type the
|
|
// `Call<T>Method` switch in `emit_llvm.zig` can't dispatch
|
|
// (anything outside void/bool/i32/i64/f32/f64/pointer), the
|
|
// compiler must emit a DIAGNOSTIC at lower time rather than
|
|
// silently producing `LLVMGetUndef` at codegen time. Without
|
|
// this guard, the chess Android touch bug shipped: an
|
|
// unsupported return type silently became `undef` and showed
|
|
// up as garbage arguments downstream.
|
|
//
|
|
// Here we declare a JNI method returning `i8` (jbyte, not yet
|
|
// wired into the call-method switch). The compile must fail
|
|
// with a clear message naming the method + return type.
