feat(profiler/behave_shell): G.1 operational.objective

Per-command intent classification via the G.0 lexicon
(`destructive > persistence > exfil > lateral > recon` precedence);
majority vote across classified commands. Skip emission below
INTENT_MIN_COMMANDS=3 classified hits. Confidence 0.40 below
INTENT_FULL_CONFIDENCE_MIN=6, 0.60 above.
