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.

// Regression: bare `$args` slice survives crossing a function-call
|
|
// boundary — both `.len` AND per-element values come through.
|
|
//
|
|
// Before the fix landed in `lazyLowerFunction`, the callee's
|
|
// `args.len` got constant-folded to the outer pack-fn mono's
|
|
// arity. `walk(args: []Any) { return args.len; }` lazily lowered
|
|
// inside `probe(..$args)`'s first mono inherited
|
|
// `pack_param_count["args"] = N` from the pack — the
|
|
// `<pack_name>.len` intercept in `lowerFieldAccess` then baked
|
|
// `ret i64 N` into walk's IR. Every subsequent shape's call to
|
|
// walk returned the same constant, regardless of the actual slice
|
|
// it received.
|
|
//
|
|
// `describe(args)` walks element-by-element so a silent
|
|
// truncation surfaces as a missing tail (or a different type at
|
|
// some position) — not just the wrong length.
|
|
//
|
|
// Walking under `#run` is intentional: the bare-`$args` slice
|
|
// carries `const_type` elements that only the interp materialises;
|
|
// LLVM emission leaves the per-element slots as undef (4A.bare
|
|
// semantics — bare-pack is comptime-only).
