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 raw value binding whose spelling shadows a builtin INTEGER type name
// (`` `i8 ``) used as an array DIMENSION through one of its fields. Field
// access on a raw value is an ORDINARY runtime field read, so `` `i8.max `` is
// a runtime value — NOT the builtin `i8.max` (= 127) and NOT a compile-time
// constant. An array dimension demands a compile-time integer constant, so the
// dimension is rejected with the same diagnostic a plainly-named runtime field
// read (`b.max`) earns — the backtick spelling changes nothing.
//
// Sibling (integer) half of the F0.11-7 fix: the compile-time INTEGER evaluator
// (`evalConstIntExpr`) misclassified a raw value-shadow receiver as the builtin
// `<IntType>.min`/`.max` accessor, silently folding 127 and fabricating a
// 127-element array. The `is_raw` guard now defers it to an ordinary field
// read, so it surfaces as a non-constant dimension instead of a silent wrong
// length.
//
// Negative companion to 0169 (the FLOAT-field narrowing half, exit 0).
//
// Regression (issue 0095 / F0.11-7).
