✨ feat: add interactive pane and command configuration to setup wizard

Expand the configuration wizard to allow users to define panes within
each window and specify startup commands for each pane. This provides
a complete tmux session setup during initial configuration.

- Add prompts for configuring panes in each window
- Add prompts for startup commands per pane
- Show full window/pane structure in summary
- Display pane commands in the final configuration review
