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.

// Phase 1 step 1.22 (PLAN-FFI.md): `#jni_call(*void)` (jobject
// return). Last return-type variant in the matrix. The returned
// jobject is a JNI LocalRef — its lifetime is bounded by the native
// frame, so chains of calls within one frame don't need explicit
// cleanup, but calls that escape (cached cross-frame) should be
// promoted via `NewGlobalRef`. For chess Android use the returned
// jobject is consumed inline by the next `#jni_call`, so no cleanup
// is needed here.
//
// CallObjectMethod lives at vtable slot 34.
