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 1.10 (PLAN-FFI.md): multi-keyword Obj-C selectors
|
|
// through `#objc_call`. Selector mangling matches clang's: every
|
|
// `:` in the source-level selector becomes a `_` in the symbol
|
|
// name of the cached SEL slot (so `initWithFrame:options:` →
|
|
// `OBJC_SELECTOR_REFERENCES_initWithFrame_options_`).
|
|
//
|
|
// The selector is opaque text to the lowering — no codegen change
|
|
// needed beyond Phase 1.6's variadic argument list. This test
|
|
// pins that the round-trip works end-to-end via class_addMethod
|
|
// + a real IMP that consumes both keyword args.
