shoney.arickathil e120129f2c feat(woc): WO-E224 — refuse a durable ref into a volatile table
Task 2 of docs/superpowers/plans/2026-08-26-table-residency.md.

- the check lives in `check_field_types`, which already runs over the raw AST
  (so the diagnostic lands at the field's own position, once per declaration)
  in Pass 2 with `syms` fully built
- only the durable -> volatile direction is refused. volatile -> durable is
  legal: the referencing row is the one that disappears, so nothing is left
  holding a stale id
- the message names both classes and both escapes, because "this is wrong" is
  less useful than "make Session durable, or declare Order volatile too"
- sees through a `?` wrapper, so `?ref S` is caught too
- code picked as 24 by sweeping `<stage>_prefix ^ "NN"` — 01-23, 25, 26 and
  50 were taken, so 24 was a genuine hole. Grepping the literal WO-E224
  would have found nothing, which is how ten codes once went missing
- catalogued in the same commit, and the completeness sweep re-run: 53
  emitted, 54 catalogued (the extra is retired WO-W201), none missing

PLAN CORRECTION: the plan's second step said to apply the same check to
`backlink` fields. Dropped — a backlink is "NOT a stored column" (ast.ml:72),
so after a restart it resolves to an EMPTY COLLECTION, which is a legal state
indistinguishable from "nothing references me". There is no id to dangle.
Implementing it would have refused correct programs; a spurious diagnostic is
worse than a missing one. A run fixture now pins that the backlink shape stays
legal, so the check cannot silently grow over-broad later.

Gates: woc-test 557/0, oop-e2e 118/0 (was 116 — one compile-fail and one run
fixture added), employee 8/0, db-actor 8/0; employee, db-bench, db-actor,
porch, log-watcher and gc-cycle all still typecheck.
