Release candidate 5.0.0-rc.27.
Regenerated against alef 0.25.59 (completes the extendr/R binding surface — kreuzberg-r now compiles). Adds the count_tokens chunking API across all bindings. Fixes: #1098 (two-column headings in elements), #1135 (PDF ligature C0 controls), #1139 (multi-language OCR from config), and a concurrency thread-pool-race. PHP package renamed to kreuzberg-dev/kreuzberg on Packagist.
See CHANGELOG.md for details.
