# Objective

- Fixes #54158 

## Solution

- The root cause is in `FileFinderDelegate::set_selected_index`: it
always sets `has_changed_selected_index = true`, regardless of whether
the selection change was triggered by keyboard navigation or mouse
hover.
- Fix: Added a separate `set_hovered_index` hook to the `PickerDelegate`
trait with a default implementation that delegates to
`set_selected_index`. The hover handler in Picker now calls
`set_hovered_index` instead of `set_selected_index`. FileFinderDelegate
overrides `set_hovered_index` to update `selected_index` without setting
`has_changed_selected_index`, so hover-triggered selection changes no
longer interfere with the `Cmd+P` auto-confirm logic.

## Testing

- Added `test_hover_does_not_set_has_changed_selected_index` in
`file_finder_tests.rs`

Release Notes:

- Fixed file finder auto-jumping to the wrong file when the mouse
hovered over a different entry after pressing `Cmd+P`
