Let's rename this function to GetEnvBoolWithAllGetters or smth like this so it's more explicit what it does. Can remove the comment from the Includes.h after that.

Calling GetEnvBoolWithAllGetters("FRANKENPHP_WORKER", ...) here can dereference AIKIDO_GLOBAL(server) via GetFrankenEnvVariable before server is initialized; guard AIKIDO_GLOBAL(server) or delay this check.

Details

✨ AI Reasoning
​The code attempts to detect a FrankenPHP warm-up request by calling GetEnvBoolWithAllGetters("FRANKENPHP_WORKER", false) early in RequestProcessor::RequestInit. GetEnvBoolWithAllGetters uses the complete set of getters including GetFrankenEnvVariable, which calls AIKIDO_GLOBAL(server).GetVar. Because the FRANKENPHP_WORKER check was moved earlier in RequestInit (before environment/server-related initialization and before LoadEnvironment/LoadLaravelEnvFile), AIKIDO_GLOBAL(server) may not be initialized yet, leading to dereferencing an uninitialized or null server object and causing a segmentation fault. This regression was introduced by moving the FRANKENPHP_WORKER check to earlier lines and by using the "all getters" helper at that point.

🔧 How do I fix it?
Add null checks before dereferencing pointers, validate array bounds before access, avoid using pointers after free/delete, don't write to string literals, and prefer smart pointers in modern C++.
