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.

// Duplicate impl detection — two impls for the same (Source, Target)
|
|
// pair are both visible from the same `xx` site (because both their
|
|
// defining modules are transitively imported). The compiler must
|
|
// emit a "duplicate xx conversion" diagnostic naming both modules,
|
|
// not silently pick one or the other.
|
|
//
|
|
// Setup:
|
|
// - 180-impl-duplicate-impl-a.sx: `impl Into(Wrap) for i64` (mul by 10).
|
|
// - 180-impl-duplicate-impl-b.sx: `impl Into(Wrap) for i64` (add 100).
|
|
// - Main imports both; the `xx 7 : Wrap` site must error.
|
|
//
|
|
// Expected exit = 1, expected output = the focused diagnostic naming
|
|
// both impl modules.
|
|
|
|
#import "modules/std.sx";
|
|
// `Wrap` is declared in the shared types module; bare-import visibility is
|
|
// non-transitive, so naming it here means importing it here (not via impl-a/b).
