Expand and update prompt injection detection patterns

Enhanced the default_patterns list in PromptInjectionDetector with more comprehensive and specific regular expressions to improve detection of prompt injection attempts, including new patterns for admin commands, system prompts, privilege escalation, and sensitive information leakage. This update aims to strengthen the robustness of the anti-prompt-injection mechanism.
