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.

// any_to_string didn't handle optionals. A struct field of type `?T`
|
|
// printed as `<?>` (any_to_string's "no case matched" default)
|
|
// because there was no `case optional:` arm, and no dispatch table
|
|
// entry mapping `?T` TypeIds to the optional category.
|
|
//
|
|
// The variadic auto-unwrap path (packVariadicCallArgs) papered over
|
|
// this for direct `print("{}\n", opt)` calls — it stringified
|
|
// optionals to either the inner value's repr or `"null"` BEFORE
|
|
// boxing as Any. But anywhere else that boxes an optional and reads
|
|
// it back through any_to_string (struct field printing,
|
|
// `xx opt : Any`, future user code) hit the `<?>` floor.
|
|
//
|
|
// Locks in the fix: each ?T variant routes through `case optional:`
|
|
// → `optional_to_string(cast(type) val)` → either the inner value's
|
|
// `any_to_string` representation or the literal `"null"`.
