### Crawler (`Crawler.java`)

Main orchestrator for crawling operations.

**Key Methods**:
```java
String execute()                // Start crawling, return session ID
void addUrl(String url)         // Add URL to queue
void cleanup(String sessionId)  // Clean up session
void stop()                     // Stop gracefully
```

**Key Fields**: `crawlerContext`, `urlFilter`, `intervalController`, `clientFactory`, `ruleManager`
