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.

// Postfix `!` (optional force-unwrap) chained directly with a member access.
|
|
// `opt!.field`, `opt!.method()`, `opt!.a.b`, and `opt![i]` must read the same
|
|
// value the bind-first form (`v := opt!; v.field`) produces — the unwrapped
|
|
// value's type has to flow into the chained access.
|
|
//
|
|
// Regression (issue 0101): chained `opt!.field` typed its receiver as
|
|
// `.unresolved` (inferExprType had no force_unwrap arm), so a string field read
|
|
// as garbage and `opt!.method()` failed to resolve at all.
