shoney.arickathil 8817fdec2a feat(compiler): ref + backlink navigation in queries (9b cont.) 
- `backlink C.f` field type: parsed, typed as `multi C`, and VIRTUAL —
  filtered out of the stored row layout (no column, omittable in
  ctor/insert), collected in clsrec.cr_backlinks
- reading a backlink (`d.staff`) lowers to DB_PROBE on the source
  class's index for the backing column (backlink_target resolves the
  (source class, index number); a backlink with no backing index has
  no efficient read)
- `ref C` navigation (`e.dept.name`) chains: a ref value is the target
  row's id, so a `Ref C` base navigates into C's fields exactly like a
  table-class value, routing to DB_GET_FIELD both in typecheck and emit
- query navigation source `from s in d.staff`: emit_query evaluates the
  nav expr to get its id-list instead of DB_SCAN; QNav typechecks with
  the range var bound to the navigation's element class
- fixture run/db-query-relations proves both directions; oop-e2e 75/0,
  woc-test 566/0, log-watcher 7/0
- still ahead for employee: order/take, group-by aggregates, projection
  records, delete + update-through-row

tests/corpus/ — the conformance spine

Fixture kinds, exact-outcome matching (byte-equal stdout / exact WO-E### / exact trap code / exact gc step+freed counts):

dir kind landed by plan
run/ compiles + runs, expected stdout 3
compile-fail/ must fail with expected WO-E### 3–4
trap/ must trap with expected code 3–4
gc/ cycle collection scenarios 3
actor/ shard/spawn/send (ASan+TSan) 4
db/ insert/select + crash/replay 5
lang/ Haxe-parity adoptions 8
sys/ fs/proc/net/time/json stdlib 9
sample-logwatcher/ ported log-watcher fixtures 10

Runner: scripts/oop-e2e.sh (plan 3, task 2 — includes the how-to-add-a-fixture doc pointer docs/plan/oop-vm/02-corpus.md).
