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 3 step 3.0: one-arg selector mangling. `addObject(o)` derives
// `addObject:` — the sx method name becomes the keyword, a single
// trailing `:` for the single arg. Selector arity (count of `:`) must
// equal sx-side arity excluding self.
//
// Pre-3.0: bails at lower.zig with the Phase 3/4 diagnostic.
