Summary

Frontend:

• Remove performant_table_charts and chat_modes from ExperimentalFeatures interface and default values
• Remove feature flag toggle controls from user config settings UI
• Remove FeatureFlagged wrapper from chat mode selector, making it always visible
• Clean up unused imports

Backend:

• Remove performant_table_charts and chat_modes from ExperimentalConfig TypedDict
• Add both flags to finished_experiments set in print.py to prevent them from being displayed as experimental features on startup

Impact

• Performant Table Charts: Charts in data tables are now always computed using the performant backend implementation
• Chat Modes: Users can now always switch between Manual, Ask, and Agent modes in the Chat sidebar without needing to enable a feature flag

These features have been tested and are stable enough for general use.
