Subject: [PATCH 1/2] fix: restore PHP 8.4 compatibility after strict_types
 corpus curation

Remove declare(strict_types=1) from files that perform dynamic type coercion
(BaseConfig, Parser, Filters, CodeIgniter, ControllerTestTrait). Cast env
values and CLI backtrace indices for PHP 8.4 type safety. Restore unsorted
imports in Foobar test fixture so sortImports tests work. Allow class
unserialization in FileHandler for FactoriesCache. Update deprecation test
to avoid strict_types TypeError on str_contains(null).
