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.

// E6BR-2 / G8 (own-wins) — a protocol method-signature CONCRETE named return type
// resolves SOURCE-AWARE, pinned to the protocol's defining module. `main`
// flat-imports `dep.sx` (`Box { a }`) AND authors its OWN `Box { m }`; the
// protocol `Provider` returns `Box` and the impl builds main's `Box`. Dispatching
// `p.get()` must type the result as MAIN's `Box`, so `b.m` resolves.
//
// Fail-before (pre-E6BR-2): the method signature went through the no-author
// `type_bridge.resolveTemplateSignatureType` wrapper (global last-wins), so the
// return typed as dep's `Box { a }` and `b.m` was `field 'm' not found on type
// 'Box'`. Pass-after: source-aware → main's `Box`, exit 0.
