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.

// Phase 1 step 1.16 (PLAN-FFI.md): two `#jni_call` sites against the
|
|
// same (class, method, sig) tuple. Today each site emits its own
|
|
// `GetObjectClass` + `GetMethodID` call (no caching yet); after 1.17
|
|
// the lowering collapses to one cached `jmethodID` per unique
|
|
// (class, method, sig).
|
|
//
|
|
// Runtime: unreachable. The JNI dispatch is all indirect through
|
|
// `*env` — no external symbol declarations — so the IR loads cleanly
|
|
// into the host JIT, and the dereferences never execute because the
|
|
// guarding `g_should_call` global stays false. A plain `if false`
|
|
// would get constant-folded, taking the `unused_jni` body out of the
|
|
// IR with it; the runtime-readable global keeps the call alive so
|
|
// the JNI lowering is visible to the IR snapshot.
