Enhance ingestion_processor.py with path normalization and strict change detection

Browse Source 
Implement path normalization to ensure consistent hash checks by converting file paths to absolute paths. Update change detection logic to handle hash comparisons more robustly, treating missing hashes as content changes for safety. This prevents redundant processing and improves efficiency in the ingestion workflow.
