The chat history JSON file contains 373 lines of test messages that appear to be generated during test runs. This test data should not be committed to the repository as it:

1. Adds unnecessary noise to version control
2. Will change frequently with every test run
3. Can be regenerated on demand

Consider adding dashboard/chat_history.json to .gitignore to prevent test data from being committed.
