- #125378: cron.lifecycle_guard: referenced-script walk fails closed on a /dev/null string literal in a suffixless python script
- PR #125396: fix(cron): exempt non-shell interpreter scripts from the POSIX reference walk by shebang, not suffix
- PR #125415: fix(cron): don't walk directly executed interpreter scripts as shell code

These issues address a bug where the cron lifecycle guard's POSIX reference walk incorrectly processes non-shell interpreter scripts (e.g. Python) as shell code, with fixes targeting shebang-based detection rather than suffix-based detection to exempt them.
