feat: add smooth focus transition animation for opacity and border

Browse source 
This adds animated transitions when switching focus between windows.
Both window opacity and border color now fade smoothly using cubic
bezier easing instead of changing instantly.

Implementation:
- Added animation_duration_focus config option (default 400ms)
- Added animation_curve_focus for cubic bezier easing curve
- Window opacity and border color animate together when focus changes
- Uses existing animation infrastructure (baked bezier points)

The feature is backwards compatible and can be disabled by setting
animation_duration_focus=0 in config file.

Changes affect 5 files with minimal additions to keep code clean.
