shoney.arickathil 936bd14bff feat(database): class-shaped row storage (iteration 9, Task 1) 
- database/src/table.{c,h}: per-shard per-class slabs (256 rows,
  malloc'd, never moved -- row addresses stable for 9b's row views),
  occupancy bitmap, LIFO slot reuse, open-addressing id hash with
  tombstones (ids never 0, never reused)
- field encoding walks the same .wob class-table kinds the VM walks:
  scalars raw (WO_NIL_SCALAR passes through), Texts copied to db_text,
  owned objects flattened recursively to db_rec, containers
  element-wise; GCREF refused at encode (the GC bulkhead, defensively)
- two one-way copy gates: insert copies VM values in, read allocates
  fresh VM values out -- no VM pointer in a slab, no slab pointer in
  the VM, proven by mutating originals after insert
- id discipline: per table per shard, S+1 step N; owner = (id-1) % N;
  N-parametric, runs at N=1 until iteration 8, tested at N=3
- choke points: wo_row_insert/wo_row_remove carry the INDEX HOOK
  sites Task 4 attaches to; nothing else mutates storage
- runtime/Makefile links database/src into every wovm + test binary
- test_table 827/0 ASan+UBSan; oop-e2e 71/0; log-watcher 7/0;
  binding doc docs/plan/oop-vm/04-db-binding.md; CODE-LOGIC.md beside
  the code; plan Task 1 checked off
