/**
 * Spec 14 R6 — Blast Radius Impact Computation
 *
 * Estimates the impact of editing a set of functions using recursive CTE
 * traversal of the caller graph. Designed for the hook path: ≤100ms budget.
 *
 * Uses targeted traversal via SQLite recursive CTE — no full adjacency load.
 * Cost scales with the BFS neighborhood size, not the codebase size.
 *
 * If latency > 100ms, the feature ships disabled-by-default.
