/**
 * Static scan guard for ruvnet/ruflo#2089 — ADR-127 Phase 1.
 *
 * Scans every `uses:` line in:
 *   - .claude/agents/github/*.md
 *   - .claude/skills/github-[name]/SKILL.md
 *   - v3/@claude-flow/cli/.claude/commands/github/[name].md
 *
 * For each ref, asserts it is either:
 *   (a) SHA-pinned  — `owner/repo@<40-hex-chars>`
 *   (b) Listed in .github/supply-chain/allowed-deps.json `actions.allowed[]`
 *
 * The `minimumVersion` sub-field is advisory (logged, not enforced by this
 * smoke).  Enforcement of the minimum version is the job of Phase 3's
 * smoke-deprecated-actions.mjs which fails on @v3 refs directly.
 *
 * Zero runtime dependencies — pure readFileSync + regex.
 *
 * Exit 0: all refs are pinned or on the allow-list.
 * Exit 1: one or more violations found (file + line reported for each).
