The full non-E2E suite (`bun run test`) only ran inside the release
workflow, and pull requests only built the Docker image, so a failing test
or type error surfaced at release time. A new Test workflow runs on every
pull request and push to main (Markdown and docs-only changes excluded):
- "Type check and build": `bun run typecheck`, `bun run typecheck:mobile`
and `bun run build:web`;
- "Regression tests": `bun run test` (bulk and integration suites).
It uses the Bun version pinned in package.json, retries `bun install` like
the other workflows, cancels superseded runs, reads the repository only,
and is limited to this repository so deployment forks spend no runners.
