[RFE] Add support to more intelligently handle errors in XML, JSON, and properties files in reflection agent

[pranavgaikwad]

Currently, we only have higher intelligence (using treesitter) for Java files in reflection agent. We should add support for xml, json and properties files but the highest priority should be to pom.xml files as we are seeing more issues in pom than anything else right now.

Here is an output from reflection agent I observed for web.xml removal:

================================== Ai Message ==================================

The updated file is incomplete. It only contains a comment and does not include the necessary XML structure or content from the original file. Please ask the junior engineer to provide a complete file.

This probably means that the agent doesn't have the correct context for the changes. We need to investigate how we can avoid this in first place.
