Feature Request: Add filtering options to getAllElements query

[dulemin]

Problem

When using element_tool with getAllElements, the only option is query: "all" which returns every element on the page. On complex pages, this leads to:

• Massive token counts (even with includeAllBreakpointStyles: false)
• Hitting the 25k token truncation limit
• Slow responses

Proposed Solution

Add filtering options to getAllElements, for example:

{
  "getAllElements": {
    "query": {
      "type": "div",           // Filter by element type
      "className": "hero",     // Filter by class name
      "parentId": "abc123",    // Get children of specific element
      "limit": 50              // Limit number of results
    }
  }
}

Or alternatively, a separate action like getElementByClassName or getElementsByType.

Current Workaround

Using selectElement → getSelectedElement for specific elements, but this requires knowing the element ID beforehand.
