amertensreplit 532f42117f Add automated tests for skill version detection
Task #13: lock in the fingerprint/relation logic behind SkillGuard's
identical/modified/new version detection with automated tests.

What was added
- Set up Vitest in artifacts/api-server (dev dep + `test` script + vitest.config.ts
  using the "workspace" resolve condition so @workspace/* resolve to source).
- Unit tests (no DB):
  - src/lib/skillFingerprint.test.ts — hashText/hashBytes stability & agreement,
    computeFingerprint stable + order-independent + sensitive to content/path/add/remove,
    jaccard overlap/symmetry/empty handling.
  - src/lib/lineDiff.test.ts — lineSimilarity ratios (identical, single-edit, disjoint,
    symmetric, CRLF), lineDiff context/add/remove with line numbers and the 2000-line cap.
- DB-backed tests (use the existing DATABASE_URL):
  - src/routes/relation.test.ts — computeRelation: identical content under a different
    name -> "identical" + check-counter (countFingerprint) increments; one-line edit to a
    single-file skill -> "modified" with sensible similarity; unrelated skill -> "new".
    Also direct computeContentSimilarity cases. Fixtures use randomized content to avoid
    collisions with shared dev data and are cleaned up afterEach.
  - src/routes/compare.test.ts — e2e GET /api/scans/:id/compare/:otherId via a live
    server: asserts unchanged/modified/added/removed statuses, sorted file order, the
    line diff for the modified file, null diffs elsewhere, and 404 for missing scans.

Production code change
- Exported computeRelation, computeContentSimilarity, countFingerprint from
  src/routes/scans.ts so the relation logic can be unit-tested. No behavior change.

Verification
- `pnpm --filter @workspace/api-server run test` -> 34 tests, 4 files, all pass.
- `pnpm --filter @workspace/api-server run typecheck` passes (rebuilt stale lib/db
  declarations via `pnpm run typecheck:libs`).
- Production build unaffected: esbuild only bundles from src/index.ts, so *.test.ts
  files are not included.
