shoney.arickathil e08c26309a feat(db2-delta): lift the resident:keys refusal, prove it end to end
- loader.c: delete the INCOMPLETE-update BAIL; durable:false +
  resident:keys stays refused (nowhere to read from)
- table.c: root-cause fix for the Text-index gap — a keys-resident
  borrow now holds ENGINE values, matching wo_row_ptr's contract
  (table.h's "no VM pointer" doctrine), not a VM-decoded row. Fixes
  idx_hash/idx_cols_equal/wo_idx_probe AND db.c's GET_FIELD/PROBE
  arms with one change; reproduced pre-fix as an ASan
  heap-buffer-overflow
- docs/examples/residency: Product is genuinely resident:keys;
  residency-accept.sh's refusal leg replaced by proving the program
  runs and stock survives a restart (11/0)
- test_wal.c: oracle test drives resident:all and resident:keys
  through the same update sequence and asserts identical rows;
  Text-indexed-update test catches the representation bug; five
  pre-existing tests corrected to the fixed contract (4746/0)
- story, README, status board, CODE-LOGIC.md updated; three known
  limitations documented: mid-drain stale reads, O(N^2) replay in
  chain length, compaction blind to per-row chain length
