Turns on python_shared_standard_library compat flag by default. I added it in #7780 and tested locally.

✅ Approved — One-line compatibility-date change that follows the existing impliedByAfterDate pattern; no issues found.

✅ All checks passed

📋 Code Quality: ✅ LGTM

The change follows the existing $impliedByAfterDate(name = "pythonWorkers", ...) pattern. Opt-in via python_shared_standard_library still works.
