Full changelog

Prevent mmap exhaustion crashes when scanning repositories with more files than (default 131 072 on Linux). The walker previously held a live per discovered file; each rayon worker now opens and drops its mapping within the processing closure, capping concurrent mappings to the thread-pool size (typically 8–32). Fixes #813
