Soham Kukreti 34c0996ee4 fix: Add CDP endpoint verification with exponential backoff for managed browsers (#1445) ...

browser_manager:
- Add CDP endpoint verification with retry logic and exponential backoff
- Call verification before connecting to CDP in `start()` method
- Graceful handling of timing issues during browser startup

test_cdp_strategy:
- Fix cookie persistence test by adding storage state management
- Fix session management test to work with managed browser architecture
- Add comprehensive CDP timing tests covering:
  - Fast startup scenarios
  - Delayed browser startup simulation
  - Exponential backoff behavior validation
  - Concurrent browser connections
  - Stress testing with multiple successive startups
  - Retry count verification

Impact:
- Eliminates browser startup failures due to CDP timing issues
- Provides robust fallback with automatic retries
- Maintains fast startup when CDP is immediately available
- Comprehensive test coverage ensures reliability

Resolves CDP connection timing issues in managed browser mode.
