feat: add console output file option for debugging and monitoring

Add comprehensive console logging to file functionality:
- CLI option --console-output-file to specify output file path
- Environment variable PLAYWRIGHT_MCP_CONSOLE_OUTPUT_FILE support
- Session configuration via browser_configure_snapshots tool
- Real-time structured logging with timestamp, session ID, and URL
- Automatic directory creation and graceful error handling
- Captures all console message types (log, error, warn, page errors)

Useful for debugging browser interactions and monitoring console activity
during automated sessions.
