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.

// Regression (issue 0060): a closure LITERAL passed directly as a bare
|
|
// function-type argument `(T) -> U` and then called inside the callee. The
|
|
// closure's underlying function takes a hidden env arg that a bare fn-ptr slot
|
|
// doesn't pass, so the compiler bridges a capture-free closure to the bare ABI
|
|
// with a generated adapter. Both block and arrow bodies. (The working contrast
|
|
// where the param is a `Closure(...)` type is examples/0302.)
