- Add nobrl,cache=strict,nosharesock,actimeo=30 mount options to the
Azure Files volume so SQLite can use byte-range locking correctly over
SMB (without nobrl, Reddit DB creation fails with 'database is locked')
- Fix _execute_neo4j_query to pass parameters as params= keyword arg
(was parameters_= which the installed neo4j driver does not accept),
restoring per-simulation graph isolation via clone_graph
