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.

// `#import` is non-transitive for TYPES, exactly like values/functions (0706):
// when A imports B and B imports C, A must NOT see C's top-level TYPE names.
// This file imports `b.sx` (which in turn imports `c.sx`) and then references
// C's type `COnly` directly — the compiler rejects it with a
// "type ... is not visible; #import the module that declares it" diagnostic.
//
// `b.sx` ↔ `c.sx` together still compile: `b_make`'s return type `COnly`
// resolves because b.sx directly imports c.sx.
//
// Regression (Phase E4): before the bare-TYPE gate went single-hop this
// 2-flat-hop type was wrongly visible (the interim transitive closure).
