🔃 refactor: Parent Message ID Handling on Error, Update Translations, Bump Agents

[danny-avila]

Summary

I updated the message handling logic in our agents controllers to prioritize overrideParentMessageId, enhanced error handling in both AskController and EditController, upgraded the @librechat/agents dependency, and cleaned up our i18n files by removing obsolete translation keys.

• Refactored AgentController so that parentMessageId is assigned using the priority order: overrideParentMessageId first, then userMessageId, then parentMessageId.
• Revised AskController and EditController error handling to include overrideParentMessageId when reporting errors.
• Upgraded the @librechat/agents package to version 2.0.5.
• Cleaned up the translation JSON files across multiple locales by removing redundant keys.

Change Type
