Align test script with CI fast-fail order

[Copilot]

bun run test only ran vitest, so lint and type errors were invisible to local test runs while CI caught them as separate gating steps.

Change

Updated the test script to mirror the CI pipeline sequence — lint → typecheck → unit tests — so bun run test fast-fails at the same points CI does:

// before
"test": "vitest run tests/*.test.ts tests/**/*.test.ts"

// after
"test": "bun run lint && bun run build && vitest run tests/*.test.ts tests/**/*.test.ts"

test:unit is preserved as a bare vitest runner for quick iteration without the pre-checks.

<issue_description>CI is catching all kinds of misc stuff and that's great. Our test suite needs to be doing that as well. Make sure it's the first thing testing tests for. Failing lint, failing typecheck etc is failing tests, so fast fail on those items. </issue_description>

Pull request overview

Updates the local test script to match CI’s fast-fail sequence (lint → typecheck → unit tests), so running bun run test locally surfaces the same failures CI would catch before executing Vitest.

Changes:

• Updated test to run lint and build (typecheck) before invoking Vitest.
• Preserved test:unit as a Vitest-only runner for faster iteration.
