agra 66bdc70bf1 test: group examples into per-category folders
Move examples/*.sx and their expected/ snapshots into per-category
subfolders (examples/<category>/...). Folder = leading filename token,
with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus
runner and LSP sweep now discover each category's expected/ dir, while
issues/ stays flat. Example 1058's repo-root-relative companion import
is made file-relative. Path strings embedded in 164 snapshots were
regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Variadic heterogeneous type packs — out-of-bounds pack index
// is a compile-time error.
//
// `foo(..$args) -> $R => args[2]` accesses the third pack
// element. When called with fewer than 3 args, the literal index
// 2 is out of bounds for the pack's actual arity. The compiler
// detects this in `diagPackIndexOOB` and emits a focused
// diagnostic at the index span — pre-fix, the fall-through hit
// the standard slice-indexing path and produced "unresolved
// 'args'" which buried the real cause.
