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.

- **Auto-box works:** change `xx i``i` in the module → prints fine.
- **Inline works:** put the same `build` body (with `xx i`) directly in the
driver's `main` (no import) → prints fine.
- **Width-independent:** `xx` on an `s32` or a `u64` both crash.
- **Width-independent:** `xx` on an `i32` or a `u64` both crash.
- So the trigger is specifically: **explicit `xx <int>` → Any as a variadic
`format`/`print` arg, in a function that lives in an imported module.**
