Optimize ignore patterns matching in `sumd/extractor.py` by compiling gitignore and sumdignore patterns into efficient compiled regular expressions with early directory segment pruning instead of repeated pure-Python `fnmatch` iterations. +3. Optimize Python module AST and complexity analysis in `_render_map_detail` by running `_analyse_py_module` across worker processes/threads in parallel, dropping map generation latency on large repositories from minutes to seconds. +4.
