Create a feedback collection mechanism

[benevolentbandwidth-nurtekin]

As Research Agent expands to new categories and user groups (e.g., universities), we need a structured way to collect user feedback.

This will help identify usability issues, model behavior concerns, and feature requests.

Goals:

1. Provide a simple way for users to submit feedback
2. Clearly communicate how feedback will be used
3. Store responses in a structured and reviewable format

Considerations

1. In-app feedback form vs. external form
2. Data storage method (file, database, external tool)
3. Privacy and transparency
4. Avoid adding friction to core user flow
