Subject: [PATCH] fix: mouse click on quickfix buffer

Previously, double-clicking a quickfix entry opened a new window,
while `<CR>` reused the existing one. This was caused by the preview
mouse mapping overriding the default `<2-LeftMouse>` behavior.

Additionally, nvim_set_current_win was called unnecessarily when
clicking within the quickfix window itself.

Changes:
- Emit `<CR>` on double left-click to ensure consistent behavior
- Remove overridden `<2-LeftMouse>` mapping
- Skip `nvim_set_current_win` if the clicked window is qflist
