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 3.2 — locked-in golden test for the default Obj-C
// selector mangling rule (Phase 3.0). One fixture covers the common
// shapes (niladic, 1-arg through 4-arg, camelCase across pieces, and
// the `#selector(...)` override). The accompanying `.ir` snapshot
// records each resolved selector string as an `OBJC_METH_VAR_NAME_*`
// constant — a change to `deriveObjcSelector` produces ONE diff that
// surfaces every affected case at once.
//
// Per the rule:
// - Niladic (arity 0): name verbatim. `length` → "length".
// - Arity N (1..): split the sx name on `_`; each piece becomes a
// keyword with a trailing `:`. Piece count must equal arity.
// - `#selector("...")` overrides the mangling entirely; the literal
// string is used as the selector. Arity is the user's contract.
