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.

// Value-slot liveness (ERR step E1.8) is analysed inside a nested lambda as its

|
// OWN boundary: `flowExpr` recurses into a lambda literal via `analyzeFnBody`.
|
|
// Reading a failable's value slot inside the lambda where its error is NOT
|
|
// proven absent is rejected — even though the lambda is never called and the
|
|
// outer function proves nothing for it.

// Negative counterpart to 1051(b): were `flowExpr`'s `.lambda` recursion

// removed, the lambda body would go un-analysed and this read would slip

// through. The program never runs (exit 1).
