shoney.arickathil 65e5739492 feat: FK restrict on delete + employee sample runs; group-by parked (9b)
- FK restrict: deleting a row a non-nullable `ref` still points at traps
  WO_T_FK (11), catchable. The compiler now records a `ref` field's
  target class in the class-table field_class metadata; the engine
  (wo_row_has_referrers) scans referencing scalar columns before a
  delete. Correctness-first full scan; the backlink-index optimization
  is recorded for later
- docs/examples/employee now COMPILES AND RUNS all six modes against a
  WAL-durable database: seed (+@unique trap across restart), report
  (per-dept aggregates + payroll), staff (unique probe + backlink +
  ref nav), raise (update-through-row), drop (FK restrict), and
  persistence via replay
- group-by SYNTAX parked to a future iteration (user decision): the
  report mode is hand-rolled from the shipped primitives meanwhile
  (same numbers). "table relations and FK" is complete
- scripts/employee-accept.sh (8 checks) + a `just employee` module;
  manifest parser tolerates iteration 9c's [share]/[[share.clients]]
  sections so `woc .` builds the sample on this branch
- fixtures trap/db-fk-restrict (code 11) + run/db-fk-restrict-catch;
  oop-e2e 79/0, woc-test 566/0, 15 runtime suites, log-watcher 7/0,
  employee-accept 8/0
- 9b story + status board updated
