Symfony bundle that retries EntityManager::flush() and custom operations when Doctrine DBAL raises a deadlock (SQLSTATE[40001], MySQL error 1213).

Features

• DeadlockRetryService: flush(?string $profile) and retry(callable $operation, ?string $profile).
• Named profiles: configure max_retries, sleep_ms, and rollback_on_deadlock per use case.
• Default profile: used when no profile name is passed.
• Detects DeadlockException and related driver errors in the exception chain.
