fix(cypher): resolve UNWIND loop variable values in MATCH...UNWIND...MERGE queries
  When a parameterized UNWIND appeared between MATCH and MERGE, the query
  router sent the entire clause to executeCompoundMatchMerge which split
  at the MERGE keyword without executing the UNWIND. The unwind variable
  (e.g. `name`) was then parsed as a bare identifier in the MERGE property
  map and returned as the literal string "name" instead of iterating the
  list values.
  Detect UNWIND between MATCH and MERGE early and delegate to a new
  handler that resolves the list, expands it, and executes the MERGE once
  per (matched-node × unwind-item) pair with proper variable substitution.
  Fixes: UNWIND $param AS var producing literal variable name over Bolt
