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.

// A type-returning FUNCTION head (`Make(i64)` where `Make :: ($T) -> Type`) is
|
|
// NON-transitive even when a DIRECT flat import authors the same name as a
|
|
// NON-function. `main` flat-imports `b.sx`; `b.sx` declares `Make :: 123` (a
|
|
// value const, not a type-fn) AND flat-imports `c.sx`, whose `Make` IS the
|
|
// type-returning function. The only TYPE-FN author of `Make` is two flat hops
|
|
// away (main → b → c), so the bare `Make(i64)` head must emit the
|
|
// "type 'Make' is not visible" diagnostic and poison — the visible 1-hop
|
|
// `Make :: 123` const must NOT vouch for it.

// Regression (Phase E4 attempt-7, finding E4-type-fn-head-hidden-by-visible-

// nonfn): before `headFnLeak` decided visibility from the ELIGIBLE FUNCTION
|
|
// authors it used the module-scope NAME predicate (`isNameVisible`), which the
|
|
// visible non-fn `Make :: 123` satisfied — so the global `fn_ast_map` type-fn
|
|
// silently instantiated and `size_of(Make(i64))` printed 8 at exit 0 instead of
|
|
// the visibility diagnostic.
