/**
 * v2.15.0 follow-up — G13: impact scan service.
 *
 * Lightweight, file-glob-based impact analysis (no AST, no type
 * checking). For a given set of changed files, predict:
 *   - which other files are likely affected (by path convention)
 *   - which business flows touch them (config-driven)
 *   - the risk level (high / medium / low)
 *   - the "must-check" list (concrete business scenarios the user
 *     must verify before shipping)
 *
 * Pure functions. The CLI wraps this with a `peaks impact scan`
 * command; `peaks impact must-check` returns the must-check list
 * subset. Persistence is per-invocation (no state file).
