v1.2.0 - nicer display + per-path context
Presentation upgrade (no functional change):
- Framed banner with an intro and a config summary.
- Cleaner, aligned menu.
- Each path now prints a section header + a 'what's happening' context block explaining the flow, and a takeaway line after it runs.
- ASCII-safe styling so it renders correctly on any Windows console.
Same single-file self-contained win-x64 build; same paths and behavior.
