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.

// Phase 6 — the canonical heterogeneous `map`, end to end. A pack-fn whose
|
|
// return type `$R` is inferred from the mapper's closure return:
|
|
// - `mapper: Closure(..sources.T) -> $R` types the lambda's params from the
|
|
// projected pack element types, and its body (`a + b`) drives `$R`.
|
|
// - `$R` is inferred at the call site from the lowered mapper's closure ret,
|
|
// bound into the mono (`-> VL($R)` ⇒ `VL(i64)`, `Combined($R, ..)` ⇒
|
|
// `Combined(i64, ..)`), and folded into the mangle.
|
|
// - `(..sources)` materializes the pack into the `(..VL(Ts))` field (per-element
|
|
// erase) and `mapper(..sources.get)` projects+spreads; `xx c` erases the

// generic-struct instance to `VL(i64)` via the generic impl's monomorphized
