feat: Add tool annotations for improved LLM tool understanding

[bryankthompson]

Summary

Adds MCP tool annotations (readOnlyHint, destructiveHint, title) to all 14 tools to help LLMs better understand tool behavior and make safer decisions about tool execution.

Changes

• Added readOnlyHint: true to read-only tools:
  • getConsoleLogs, getConsoleErrors, getNetworkErrors, getNetworkLogs
  • getSelectedElement
  • runAccessibilityAudit, runPerformanceAudit, runSEOAudit
  • runNextJSAudit, runDebuggerMode, runAuditMode, runBestPracticesAudit
• Added destructiveHint: true to tools that modify state:
  • takeScreenshot (creates files)
  • wipeLogs (clears data)
• Added title annotations for human-readable display
• Bump MCP SDK dependency from ^1.4.1 to ^1.7.0 for annotation support

Why This Matters

Tool annotations provide semantic metadata that helps MCP clients:

• Safety automation: Clients like Claude Code can auto-approve readOnlyHint: true tools without confirmation
• UI/UX improvements: Clients can display appropriate warnings/icons for destructive operations
• Tool discovery: Clients can filter/group tools by characteristics

Testing

• Server builds successfully (npm run build)
• Live verification: Started server and confirmed tools/list returns annotations for all 14 tools
• Annotation values match actual tool behavior (read-only vs destructive)

Verification Output

Total tools: 14
