Subject: [PATCH] feat(compiler): replace hardcoded autoloader path with
 dynamic resolution

- Replace direct require of TYPEPHP_ROOT_PATH . '/vendor/autoload.php' with resolveComposerAutoloader() function
- Add new resolveComposerAutoloader() function to locate Composer autoloader from multiple candidate paths
- Support both source checkout and packaged SDK environments by checking TYPEPHP_ROOT_PATH and PHP_HOME
- Implement fallback mechanism to search for vendor/autoload.php in different locations
- Add detailed error reporting when autoloader is not found with specific search paths
- Include installation instructions in error output when dependencies are missing
- Exit with error code 1 when autoloader cannot be located
