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 generic value parameter (`$K: u32`) binds a literal (`Vec(3, i64)`) and an
// integral-float named const (`Vec(L, i64)` with `L : f64 : 4.0`) to the same
// integer a plain `4` would — the value-param arg folds through the shared
// const-int evaluator, so the integral-float rule (F0.4 attempt 8, Agra ruling)
// reaches value params too. The folded value is the array length `[K]i64`.
//
// The bind is range-checked against the declared `u32` (an out-of-range arg is a
// clean compile error — see 1134); a valid in-range value binds normally.
#import "modules/std.sx";
Vec :: struct ($K: u32, $T: Type) { data: [K]T; }

b : Vec(L, i64) = ---; // integral-float named-const value param → 4
print("a.len={} b.len={}\n", a.data.len, b.data.len); // 3 and 4
