• Closes panda debug 's *.ast.json should include endColumn and endLine #3407

📝 Description

Add endLineNumber and endColumn fields to the AST JSON output generated by panda debug command. This provides complete position information for detected CSS usage locations
in source files.

⛳️ Current behavior (updates)

The *.ast.json files generated by panda debug currently include only start position information:

• line: Start line number
• column: Start column number

This incomplete position data makes it difficult to anlyze the AST.

🚀 New behavior

The AST JSON output now includes complete position information:

• line: Start line number
• column: Start column number
• endLineNumber: End line number ✨ NEW
• endColumn: End column number ✨ NEW

Example output:

{
  "box": {
    "type": "map",
    "node": "JsxSelfClosingElement",
    "line": 1,
    "column": 1,
    "endLineNumber": 1,
    "endColumn": 29,
    "value": {
      "color": {
        "line": 1,
        "column": 17,
        "endLineNumber": 1,
        "endColumn": 26,
        "value": "red.200"
      }
    }
  }
}

💣 Is this a breaking change (Yes/No): No

This is a non-breaking change. It only adds new fields to the JSON output while preserving all existing fields. Any tools currently reading the AST JSON will continue to work
unchanged, and can optionally use the new fields.

📝 Additional Information

• The underlying infrastructure (getNodeRange()) already computed these values - they were simply not being exported
• Added unit test with inline snapshot to verify the new fields are present
