feat(v2.7.0): Smart Rate Limit Management & Multi-Token Configuration

Major Features:
- Multi-profile GitHub token system with secure storage
- Smart rate limit handler with 4 strategies (prompt/wait/switch/fail)
- Interactive configuration wizard with browser integration
- Configurable timeout (default 30 min) per profile
- Automatic profile switching on rate limits
- Live countdown timers with real-time progress
- Non-interactive mode for CI/CD (--non-interactive flag)
- Progress tracking and resume capability (skeleton)
- Comprehensive test suite (16 tests, all passing)

Solves:
- Indefinite waiting on GitHub rate limits
- Confusing GitHub token setup
