Code Review

This pull request updates the release package test script test_release_package.sh by adding a step to install Python runtime dependencies, increasing compilation parallelism to -j16, and appending || true to the binary check command. The review feedback highlights several critical issues: first, using ${version} instead of ${version_rc} when finding files and changing directories will cause failures during release candidate verification under set -u. Second, referencing ${PYTHONPATH} directly under set -u will trigger an unbound variable error if it is not already set, which can be resolved using ${PYTHONPATH:-}. Third, hardcoding -j16 for compilation may lead to OOM or CPU starvation on resource-constrained environments, so dynamically scaling using nproc is suggested. Finally, replacing backticks with $(...) for command substitution is preferred for better readability.
