Improve status output

[cmtonkinson]

Summary

Implements #6 - Improves the gov status output with enhanced visual layout for better clarity and efficiency.

Changes

Two-Column Layout

• Left: Supervisor status in bordered box
• Right: Workers status in bordered box
• Saves ~40% vertical space for operational status
• Only activates when terminal width >= 100 columns (graceful fallback to single-column)

Clear Visual Separation

• Each major section now has clear bordered boxes (requested: "literally draw boxes around them")
• Distinct border colors for different sections
• Better visual hierarchy and scanability

Recent Supervisor Logs

• New section showing last 5 lines of supervisor logs
• Placed below operational status, before tasks
• Makes it easier to see what's happening without running gov why
