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.

// Variadic heterogeneous type packs — step 4A end-to-end
|
|
// smoke. Exercises the FULL chain step 5's generic
|
|
// `Into(Block)` impl needs:
|
|
//
|
|
// 1. A pack-fn that passes its bound `$args` to a builder
|
|
// via `#run` / `#insert` (here `#run` for simplicity).
|
|
// 2. The builder receives a `[]Type` slice and walks it,
|
|
// calling `type_name(list[i])` per position.
|
|
// 3. `type_name(list[i])` is the DYNAMIC form — the index_expr
|
|
// argument can't be statically resolved at lower time, so
|
|
// the lowering emits a `callBuiltin(.type_name, ...)` that
|
|
// the interp's arm handles by reading the runtime
|
|
// `Value.type_tag(TypeId)` and returning the per-position
|
|
// name.
|
|
//
|
|
// The smoke demonstrates that step 4's full surface — bare
|
|
// `$args` (whole pack as []Type) + dynamic reflection
|
|
// intrinsics + per-position type discovery at interp time —
|
|
// hangs together end-to-end. This is the foundation step 5's
|
|
// builder-driven generic Into(Block) impl rests on.
