Introduce `frankenphp_min_memory_mb` option to enforce a minimum memory threshold before handling new requests. This prevents running workers when memory is critically low, enhancing stability. Option is configurable via environment variables or runtime options. Default value is -1 which disables this new functionality.

There was a problem hiding this comment.
Thank you. Great idea. But I made some minor comments
- Skip first loop is not necessary since it's a do while (so always first cycle) - Handle numeric-only memory_limit (bytes) in default case
