- Pre-compile CHINESE_RE and ENGLISH_RE at the module level. - Update count_words() to use the pre-compiled patterns. - This avoids repeated compilation (or internal cache lookups) during each call, improving efficiency for large books with many chapters and paragraphs.

⚡ What: The optimization pre-compiles regex patterns for Chinese characters and English words at the module level in
scripts/zlibrary/epub_converter.py.🎯 Why: Previously, these regex patterns were compiled on every call to
count_words, which is called inside loops for each chapter and paragraph. While Python has an internal regex cache, pre-compiling is a best practice that ensures maximum efficiency and avoids the overhead of cache lookups.📊 Measured Improvement: In a synthetic benchmark of 1,000 calls on a large text string, the improvement was negligible (~0.68%), likely because the regex patterns are simple and Python's internal cache already handles them well. However, this change is a standard performance best practice and ensures consistent efficiency regardless of the cache's state or the complexity of the patterns.
