/**
 * visus_read MCP Tool
 *
 * Extracts clean article content from a web page using Mozilla Readability,
 * stripping navigation, ads, and boilerplate. Full prompt injection sanitization
 * and PII redaction applied before content reaches the LLM.
 *
 * CRITICAL: ALL content MUST pass through the sanitizer. This cannot be bypassed.
 *
 * Pipeline order:
 * 1. Playwright renders page (full JS execution)
 * 2. Reader extracts main content (reduces input size)
 * 3. Sanitizer runs on clean text
 * 4. Token ceiling applied (24,000 token cap)
