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.

// Chained foreign-class method dispatch: `Cls.static().instance(...)`
// resolves the inner call's return type so the outer dispatch's
// receiver type is known. Pre-fix this collapsed to i64 in
// `inferExprType`, the foreign_class_map lookup missed, and lowering
// emitted `error: unresolved 'init'` (or 'initWithWindowScene' etc.)
// — see issues/0043 for the chess uikit.sx C4 migration that hit it.
//
// Two return-type shapes covered: explicit `*ClassName` (alloc here)
// and `*Self` (init). Both must propagate through the chain so the
// next `.method(...)` finds the foreign-class declaration.
