fix(ci): build testkit dist before adapter/release tests that import it

The memory + postgres adapter conformance tests import
@razroo/parallel-mcp-testkit, which resolves (via npm workspaces) to
testkit/dist/index.js. On a clean checkout the dist/ directory is
empty, so vitest fails with "Failed to resolve entry for package
@razroo/parallel-mcp-testkit".

Build testkit before those tests run in both .github/workflows/ci.yml
(main + compat-sqlite) and .github/workflows/release.yml.

Surfaced by the v0.4.0 release run (failed at "Test (all workspaces)").
Local runs masked it because a prior pack:check left dist/ populated.
