shoney.arickathil ed45ac7c06 fix(arena): poison-on-free — a freed block can never pass for a live object (language 44) 
- wo_arena_free stamps the header: class_id = WO_CLS_FREED (0xFFFFFFFF), shard_id = 0xFFFF, flags/pad = 0
- freelist link moves from offset 0 to offset 8 so the poison survives on the list; wo_arena_alloc pops from offset 8
- wo_drop_obj aborts first on a poisoned header: a double free is a diagnostic, not a catchable state
- WO_CLS_FREED defined in wob.h beside the builtin id space
- test_arena: test_poison_on_free (poison stamped, LIFO chain through the relocated link, class drains to a fresh bump) — 17/0
- full suite SUITE_ALL_ZERO, wovm + wovm_asan rebuilt, just db-actor 10/0 (lang-41 5x marshal gate unchanged)
- story 44 status: done; board row + dependency graph L44 (41 -.follow-up.-> 44)
