Keep make test from collecting tests in nested checkouts (closes #25)

vitest does not read .gitignore when finding tests, so a checkout nested under .claude/ had its whole test/ tree run as part of this suite. vitest.config.ts adds .claude/** to vitest's default excludes. The new packaging test plants a nested checkout in a temp directory and fails if vitest, run with this config, would collect it. Model: opus-5-5
