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.

// fix-0102c F1 (issue 0102): two flat FILE imports each author same-name free
// functions whose VARIADIC SHAPE differs. `combine` is fixed-arity in a.sx
// (the first-wins winner) but variadic in b.sx (the shadow); `pick` is the
// reverse. Each module's bare call must pack arguments against ITS OWN
// author's signature — not the first-wins author's. Pre-fix the call path
// re-fetched the first-wins AST by name to drive variadic packing, so b.sx's
// variadic `combine` was packed as if fixed (and its fixed `pick` as if
// variadic) → wrong lowering. Regression for the F1 review finding.
