feat: IACE 28 operational hazard patterns (HP066-HP093)

Fault Clearing (HP066-HP072): Jammed parts releasing, hose bursts,
unexpected restart, stored energy, intervention in running machine,
material jam, falling parts during fault clearing

Maintenance (HP073-HP079): Missing LOTO, falls from platforms,
hot parts contact, hazardous substances, electric shock, ergonomic
access, uncontrolled hydraulic lowering

Setup/Changeover (HP080-HP085): Crushing during tool change, burns
from hot tools, heavy tool drops, unintended stroke in setup mode,
wrong parameters, test cycle hits personnel

Transport/Install/Decommission (HP086-HP090): Machine tipping,
crushing during installation, uncontrolled commissioning movement,
residual media, sharp edges

Cleaning (HP091-HP093): Slipping, chemical exposure, draw-in

Lifecycle keywords expanded: werkzeugwechsel, stoerung, fehlersuche,
klemm, blockier, stau → trigger fault_clearing phase patterns
