fix(crc32c): escape the version dot and anchor the pyenv check regex (#17555)
### Problem The OS X python wheel build script (`build_python_wheel.sh`) checks if a Python version is installed in `pyenv` before building: ```bash if [ -z "$(pyenv versions --bare | grep $version)" ] ``` When $version is 3.14, this expands to grep 3.14. Because the dot (.) is not escaped, it is treated as a wildcard and will also match the substring 3.13.14 (which contains 3.<any char>14 at the end). This results in a false positive, causing the script to skip compiling Python 3.14. The script then fails when executing pyenv shell 3.14 with a "version not installed" error. ### Solution Escape the version dots in bash: `${version//./\.}.` Anchor the grep match with line start (`^`) and word boundaries (`\b`) to ensure it only matches the exact version line (e.g. `^3\.14\b` instead of matching `3.13.14`). Applied this fix to both `build_python_wheel.sh` and `publish_python_wheel.sh`. Blocks: #17642
