Sets the maximum execution time in milliseconds for regular expression pattern matching in LiveQuery. This protects against Regular Expression Denial of Service (ReDoS) attacks where a malicious regex pattern could block the event loop. A regex that exceeds the timeout will be treated as non-matching.

The protection runs each regex evaluation in an isolated VM context with a timeout. This adds approximately 50 microseconds of overhead per regex evaluation. For most applications this is negligible, but it can add up if you have a very large number of LiveQuery subscriptions that use $regex on the same class. For example, 10,000 concurrent regex subscriptions would add approximately 500ms of processing time per object save event on that class.

Set to 0 to disable the timeout and use native regex evaluation without protection. Defaults to 100.
