- Test load from YAML file with multiple proxies
- Test load from environment variable (backward compatibility)
- Test round-robin rotation
- Test empty pool handling
- Test single proxy handling
- Test ProxyEntry defaults

RED phase: tests fail because proxy_pool module does not exist yet

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- ProxyEntry: tracks proxy state, failures, and recovery
- ProxyPoolConfig: YAML configuration model
- ProxyPool: manages multiple proxies with round-robin rotation
- from_yaml(): load from ~/.kb_proxies.yaml
- from_env_fallback(): backward compatible env var loading
- get_next_proxy(): round-robin with lazy recovery check

Implements PROXY-01 (multi-proxy config) and PROXY-02 (rotation)

- Add proxy_pool parameter to ZhihuCrawler constructor
- Add _current_proxy tracking for health check feedback
- Implement _parse_proxy_url static method for URL parsing
- Implement _on_request_success/failure for proxy health feedback
- Prioritize proxy_pool over config.proxy for multi-proxy support
- Maintain backward compatibility with single proxy config

Tests:
- test_crawler_accepts_proxy_pool
- test_crawler_without_proxy_pool (backward compatibility)
- test_parse_proxy_url (HTTP, auth, SOCKS5)
- test_proxy_pool_takes_priority_over_config
