Add labels to tmux panes for better navigation

[bborn]

Summary

• Add pane border labels to display pane names at the top of each pane
• Label the main view panes as "Tasks" (top) and "Copilot" (bottom)
• Label the task detail view panes as "Details" (top), "Claude" (bottom-left), and "Shell" (bottom-right)
• Ensure labels are properly reset when switching between main view and task detail view

Implementation Details

The implementation adds tmux pane titles using select-pane -T and enables pane border status display with pane-border-status top. This provides clear visual indicators of each pane's purpose:

Main View:

• Tasks: The kanban board showing all tasks
• Copilot: App-wide Claude assistant for task management

Task Detail View:

• Details: Task metadata and logs (15% height)
• Claude: Task-specific Claude session (42% width)
• Shell: Working directory shell (42% width)

Test plan

• Build succeeds without errors
• Start the app and verify "Tasks" and "Copilot" labels appear in main view
• Enter a task detail view and verify "Details", "Claude", and "Shell" labels appear
• Exit task detail view and verify labels reset back to "Tasks" and "Copilot"
• Verify pane border styling is consistent and visually clear
