Detailed Description

Implements OP_DATE_FORMAT to format an epoch milliseconds timestamp using strftime.

Behavior:

Pops fmt string, then milliseconds since Unix epoch (int).
Formats the local time according to fmt and pushes a string.

Errors:

If types are wrong, prints error and pushes empty string to keep stack safe.
