agra d8076b9333 lang: rename signed integer types sN -> iN
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.

// Module B authors a same-name `Box` shadow whose field SELF-REFERENCES its own
// name (`next: *Box`). Pre-fix the self-ref resolved to A's `Box` (registered
// first under the bare name), so `next.*.y` failed with "field 'y' not found on
// type 'Box'". The shadow's slot is now reserved BEFORE its fields resolve, so
// `*Box` binds to B's OWN nominal TypeId and the deref sees B's `y`.
Box :: struct { y: i64; next: *Box; }
b_chain :: () -> i64 {
tail := Box.{ y = 42, next = null };
head := Box.{ y = 1, next = @tail };
// Walk the self-referential link; reads B's own `y`, not A's `x`.
return head.next.*.y;
