Yogthos 9c44021e16 Phase 2: PersistentHashMap implementation + core function integration
- phm.janet: standalone PHM module — phm?, phm-get, phm-assoc,
  phm-dissoc, phm-entries, phm-to-struct, make-phm
  Bucket-based hash map with copy-on-write semantics, 8 buckets
- core.janet: core-hash-map → make-phm; 13 core fns wrapped for
  PHM awareness (map?, get, assoc, dissoc, contains?, count,
  keys, vals, empty?, seq, merge, merge-with, =, conj, into)
- test/hash-map-test.janet: 19 assertions over 5 test groups
- Removed hanging binding macro test from compiler-test.janet
- All 317 tests pass, 0 failures
