/**
 * UI/UX Full Dive v2 — Advanced Tools
 *
 * Deep interaction testing, screenshot capture, design auditing,
 * backend context linking, changelog tracking, and walkthrough generation.
 *
 * These tools complement the base dive tools (uiUxDiveTools.ts) and work
 * with the MCP Bridge (playwright-mcp) for browser automation.
 *
 * Architecture:
 * - Agent uses MCP Bridge to drive the browser (navigate, click, type, screenshot)
 * - These tools provide structured storage and analysis on top of bridge actions
 * - Screenshots are saved to disk + thumbnail stored in DB for fast retrieval
 * - Interaction tests define preconditions → steps → expected/actual per step
 * - Design audits compare computed styles across components for inconsistencies
 * - Backend links connect UI components to API endpoints, Convex functions, DB tables
 * - Changelogs track before/after with screenshots when fixes are applied
