Pull request overview

This PR fixes the TUI selection list behavior so users can filter items by name and don’t accidentally exit the program while applying a filter (addressing #772).

Changes:

• Enabled Bubble List filtering by returning the item’s string value from FilterValue().
• Adjusted Enter-key handling so Enter applies the filter first (when filtering), and only selects/quits when not in filtering mode.

In the non-filtering path, the code calls tea.Quit even when SelectedItem() is nil or not of type Item (i.e., ok == false). That can still exit the TUI with an empty Choice, which upstream turns into "no ... selected" errors (e.g., when a filter yields 0 results). Consider only quitting when an item is successfully selected; otherwise keep the program running (or set an explicit abort state) so the user can adjust the filter instead of exiting with an error.
