Problem: initialize_wp_cache() was capturing debug output from system detection,
filling cache file with [INFO]/[OK] messages instead of just WordPress paths
Solution: Redirect stderr when calling get_wp_search_paths to suppress debug output
This caused 12 extra lines of garbage in the cache, appearing as '.' entries
when the script tried to process them as file paths.
