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.

// A comptime `#run` global initializer that yields a function reference cannot
// be serialized to a static constant: at global-init time (Pass 0) functions
// are not yet declared, and the comptime serialization path has no later
// re-emit, so the func_ref can never resolve to a real function pointer. The
// compiler must reject this with a diagnostic AND a CLEAN non-zero exit — never
// print the error and then fall through into an undef initializer that crashes
// (pre-fix: the diagnostic printed, emission continued, and the JIT segfaulted
// calling through the undef pointer → exit 134).
// Regression (issue 0079 follow-up): every global-init serialization bail now
// routes through `failGlobalInit`, which sets the halt flag so the driver aborts
// after emit() instead of shipping the placeholder.
// Expected: "comptime init of 'fp' produced a reference to function 'add'…";
// exit 1, no segfault.
