astroid 4.3.4 makes pylint report possibly-used-before-assignment in dirac_admin_add_site.py, because a branch that ends in DIRACExit(-1) is not known to terminate. Annotating DIRAC.exit with NoReturn lets pylint treat every DIRACExit call as the end of its branch. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

pylint fails on every PR since astroid 4.3.4 reached conda-forge (8 Oct):
DIRAC.exit()(imported asDIRACExit) wrapssys.exitbut is not annotated, so pylint cannot tell that a branch ending inDIRACExit(-1)stops there. astroid 4.3.3 happened to hide this. AnnotatingexitwithNoReturnfixes this call site and every otherDIRACExitcall.Checked in a conda env built from
environment.yml(pylint 4.1.2): the error appears with astroid 4.3.4 and not with 4.3.3 (diracx 0.5.0 vs 0.6.0 makes no difference), andpylint -j 0 -E src/is clean with this change.Same change for each branch: rel-v8r0, rel-v9r0, integration (hence
sweep:ignore).BEGINRELEASENOTES

FIX: annotate DIRAC.exit as NoReturn so pylint knows DIRACExit ends a branch
