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 2: typed pack indexing.
|
|
//
|
|
// `args[$i]` (with `$i` a comptime-known integer) inside a pack-fn
|
|
// body should resolve to the i-th call-site argument with its
|
|
// CONCRETE type, not the boxed `Any` that today's `[]Any` slice
|
|
// path yields. Without typed access, downstream operations on the
|
|
// element (field access, typed coercion, passing to a typed slot)
|
|
// either fail with "field 'X' not found on type 'Any'" or silently
|
|
// box/unbox through Any.
|
|
//
|
|
// This file pins today's failure: `args[0].x` on a struct-typed
|
|
// call arg trips "field 'x' not found on type 'Any'" because the
|
|
// AST-level type inference for `args[0]` returns Any.
|
|
//
|
|
// Next commit teaches `lowerIndexExpr` to detect a pack-name base
|
|
// with a comptime-int-literal index and substitute the i-th
|
|
// call-site arg's lowered value directly — propagating the call
|
|
// arg's real type through field access, typed assignments, and
|
|
// further indexing.
