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 — follow-up #1 (mixed
|
|
// `$comptime + ..$args` pack-fn signatures).
|
|
//
|
|
// Today's `isPackFn` rejects pack-fns that mix any other
|
|
// comptime param with the trailing pack — they fall through
|
|
// to the inline `lowerComptimeCall` path. The inline path
|
|
// doesn't bind non-string comptime params as runtime locals,
|
|
// so a body that uses both `$tag` (i32) AND `..$args` fails
|
|
// at the bare-name lookup of `tag`.
|
|
//
|
|
// Next commit relaxes `isPackFn` to accept "exactly one
|
|
// trailing pack + any number of non-pack comptime params" and
|
|
// `monomorphizePackFn` folds the comptime VALUES into the
|
|
// mangled name (so distinct calls of `tagged(7, ...)` vs
|
|
// `tagged(9, ...)` get distinct monos), then binds the
|
|
// comptime values as both comptime substitutions and runtime
|
|
// locals (for body code that references them by name).
