Replace tmux popups with split windows for better log navigation

- Change J/L log commands from popups to split windows for scrolling support
- Change rebuild command from popup to split window with consistent 30% height
- Add auto-close behavior with bash -c "command; exit" wrapper for logs
- Add "press any key to close" prompt with visual separators for rebuild
- Enable proper tmux copy mode and navigation in all split windows

Users can now scroll through logs, copy text, and resize windows while
maintaining clean auto-close behavior for all operations.
