Implements scripts/bus-factor.mjs — a standalone Node.js CLI that shells out to git log --numstat to collect per-file, per-author commit stats, then computes bus-factor scores (number of contributors with >10% ownership) for every source file in server/src/, client/src/, and db/migrations/. High-risk files (bus-factor=1) are surfaced prominently in the default report. A --json flag emits machine-readable output for CI. Pure analysis functions (parseGitLog, computeOwnership, scoreFiles, repoStats) are unit-tested with Vitest (19 tests, all passing). No new runtime dependencies — only Node.js built-ins and git are required.
