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.

// Variadic heterogeneous type packs — step 4A final-slice
// follow-up. `type_name(<dynamic-arg>)` where the argument is
// NOT a static type expression (e.g. `list[i]` indexing into
// a `$args`-derived `[]Type` slice) silently folded to "i64"
// because `resolveTypeArg`'s catch-all `else => .i64` lied —
// the kind of silent unimplemented arm the project's REJECTED
// PATTERNS forbid.
//
// The fix: `tryLowerReflectionCall` now splits static vs
// dynamic args via `isStaticTypeArg(node)`. Static → fold to
// const_string at lower time (today's fast path). Dynamic →
// emit `callBuiltin(.type_name, [arg_ref])` for the interp's
// runtime arm to handle.
//
// Type values are comptime-only — the dynamic path only works
// inside a comptime context (`#run` / `#insert`). The test
// runs `walk(42, "hi")` at `#run` time and prints the result.
