Risk Heat Map Builder

Builds a structured risk heat map scoring each identified risk on a 5x5 likelihood-by-impact matrix, assigning low/medium/high/critical ratings, producing a ranked priority list, and recommending a treatment approach (accept/mitigate/transfer/avoid) for every risk. Use when a list of risks needs to be scored, visualized, prioritized, or assigned treatment strategies for a risk register, assessment, or review.
