Visual Highlighting Fixes:
- Apply selection highlighting to individual text spans instead of entire paragraph
- Eliminates highlighting of empty space below services on single-service hosts
- Selection now only highlights actual service text content
Selection Logic Improvements:
- Add proper bounds checking in select_next() to prevent invalid selections
- Automatically clamp selection index when services are updated
- Add debug logging to track selection state and movement
Bounds Safety:
- Ensure selection index stays valid when service lists change
- Prevent out-of-bounds access during service updates
- Reset selection to last valid index when services are removed
This fixes the issues where:
1. Single service hosts showed empty space highlighting
2. Multi-service hosts had no visible selection cursor
3. Selection could become invalid when services changed
