* Default function timeout (in seconds) for the Function node.
* A value of 0 indicates no timeout is applied, meaning the function can run indefinitely.
*
* The default function timeout is designed to prevent blocking code in function nodes,
* which could otherwise lead to a stalled or unresponsive main thread. For example,
* the following code would block the event loop indefinitely:
*
* `while(1) {}`
*
* By specifying a `defaultFunctionTimeout`, such scenarios can be mitigated,
* ensuring that long-running or infinite loops are terminated automatically after
* the specified timeout duration.
*
* Note: If both `defaultFunctionTimeout` and `functionTimeout` are defined in the
* settings file, `functionTimeout` takes precedence, providing a more granular
* control for individual function nodes.
