"""Phase 13 site 1: narrow 'except Exception' in _get_sentence_transformers.

Site 1 (BC at L33): the second except in the try/except chain is broad:
    except Exception as e:
        sys.stderr.write(...)
        sys.stderr.flush()
        raise e

Per TIER1_REVIEW: catch + log + re-raise is Pattern 2 of the styleguide.
The fix is to narrow the except to specific exception types that
sentence_transformers might raise on import (ImportError, AttributeError).
