AutoFix: Inefficient file processing in loops

Category: performance
Severity: medium

Issue

The hotspot comparison logic reads the entire current-files.txt for each file being processed, resulting in O(n²) complexity. This could become a performance bottleneck for repositories with many files.

Fix

The fix addresses the O(n²) complexity issue by pre-processing the JSON files into TSV lookup tables using jq, then using grep for efficient lookups instead of re-parsing the entire JSON for each file. This reduces the complexity from O(n²) to O(n) where n is the number of files being processed.
