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 2.6: indexing a pack with a
|
|
// RUNTIME index is a compile error.
|
|
//
|
|
// Per locked Decision 1, a pack is comptime-only and has NO runtime
|
|
// representation — so `args[i]` is valid only when `i` is a compile-time
|
|
// constant (a literal, or an `inline for` cursor). A runtime index (here a
|
|
// `while`-loop counter) must produce a clear diagnostic, not the confusing
|
|
// "unresolved 'args'" the slice-index fall-through used to give. To walk a
|
|
// pack, use `inline for 0..args.len (i) { ... }`, which unrolls so each
|
|
// `args[i]` is a comptime index.
