fix(bolt,cypher): resolve 3 Cypher correctness issues found via Bolt client
  1. Multi-hop MATCH + OPTIONAL MATCH returns 0 rows:
     executeCompoundMatchOptionalMatch only parsed the first node in a
     traversal pattern, seeding the OPTIONAL MATCH with wrong variable.
     Now executes the full initial traversal and uses result rows as seeds.
  2. Write counters in ResultSummary always return 0:
     Bolt PULL/DISCARD completion metadata never included the "stats" map.
     Added Stats field to bolt.QueryResult, populated it from the cypher
     executor, and emit Neo4j-compatible stats in both PULL and DISCARD
     SUCCESS messages.
  3. RETURN after DETACH DELETE returns null for non-COUNT expressions:
     applyDeleteReturnProjection only evaluated COUNT() and skipped all
     other return items. Now resolves string literals, property accesses,
     and bare variable references correctly.
