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.

// `process.exit` (ERR step E4.1): immediate process termination with an exit
// code. No `defer` / `onfail` cleanup runs and no error-trace frames are pushed
// — it's POSIX `_exit(2)`. Here a runtime call exits 42; the line after never
// runs. (sx `print` writes unbuffered via `write(2)`, so the "starting" line
// still appears despite `_exit` skipping the stdio flush.) Expected exit: 42.
