fix: resolve Windows terminal corruption after Ctrl+C interrupts

- Reorder reset operations to restore console mode before sending ANSI sequences
- Add terminal reset at the start of each interactive loop iteration
- Fix ANSI escape codes being printed as literal text on Windows
- Ensure ENABLE_VIRTUAL_TERMINAL_PROCESSING is enabled before ANSI reset
- Add detailed comments explaining critical ordering requirements for Windows terminal state
