Pull request overview

This PR adds validation for JSON Pointer and XPath exclusion expressions in the IncrementalWriteFilter, ensuring that invalid expressions are caught at build time rather than during document processing. The changes include comprehensive test coverage for both valid and invalid exclusion scenarios.

Changes:

• Added validation methods for JSON Pointer and XPath expressions in the IncrementalWriteFilter.Builder
• Created a new test class to verify that invalid exclusion expressions trigger appropriate errors
• Added test coverage for cross-format exclusion handling (JSON exclusions applied to XML documents)
