Subject: [PATCH] chore: add test coverage measurement
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wire coverage collection, reporting, and a non-failing CI signal to
establish a baseline. No threshold gate — coverage never blocks merge.

- jest.config.js: root-level collectCoverageFrom across src/**, with
  text-summary/lcov/json-summary reporters
- package.json: add test:coverage script (test left untouched)
- validate-pr.yml: run test:coverage, upload coverage/ as artifact
  (Linux-only, non-blocking)
- .gitignore: ignore /coverage

Baseline: 17.15% lines, 17.67% statements, 13.18% branches,
11.87% functions (282 pass, 2 skip).
