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.

// Impl visibility — an `impl Into(...) for ...` is registered into
|
|
// the global impl table when its module is imported anywhere in the
|
|
// program, but is only **visible** from files that themselves
|
|
// transitively import the impl's defining module.
|
|
//
|
|
// Setup:
|
|
// - 179-impl-visibility-impl.sx declares an `impl Into(Wrap) for i64`.
|
|
// - 179-impl-visibility-user.sx tries `xx 7 : Wrap` but only
|
|
// imports the shared types — NOT the impl module.
|
|
// - The xx at the user-file site must produce a "no visible xx
|
|
// conversion" diagnostic, not silently fall through to whatever
|
|
// was registered in another module.
|
|
//
|
|
// The diagnostic is the success criterion — the compile error is the
|
|
// expected output. Tests/expected/.txt captures it; .exit is 1.
