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.

// Comptime return-trace resolution (ERR E3.0 slice 3b). A `#run` block that
// raises, propagates via `try`, and catches the error, then formats the trace
// with `trace.print_current()`. At comptime a frame is a packed
// `(func_id, span.start)` (not a `*Frame`); the interpreter's `.trace_resolve`
// unpacks it and resolves `file:line:col` via the module + source map — so the
// comptime trace prints the same `func at file:line:col` form as a runtime one.
// Expected exit: 0 (the error is caught; the trace is printed during the build).
