Subject: [PATCH] fix(ci): never fail issue labeler on unknown labels

The labeler LLM is told to pick from a fixed set of labels, but several
of those labels do not exist in the repo (e.g. 'compile',
'attention-backends', 'torchao', 'new-pipeline/model'). Applying any of
them with 'gh issue edit --add-label' fails the whole job, so most bug
reports end up with no labels at all (issue #14377: 'needs-env-info').

Filter the model output against the repo's actual label list before
applying, and emit a warning for any label that does not exist instead
of failing the run.
