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.

// Failable error-slot discard rejection (ERR step E1.8 — discard slice). The
|
|
// error slot of a value-carrying failable cannot be dropped on a bare
|
|
// destructure: it must be bound (`v, err := …`) and handled, or the failure
|
|
// routed through `try` / `catch` / `or value` (all of which strip the error
|
|
// channel, so they don't reach this check). Two rejected shapes here:
|
|
// (1) omitting the error slot entirely (fewer names than slots), and
|
|
// (2) binding it to `_`.
|
|
// This file is expected to FAIL compilation (exit 1).
