Enforce build+tests; add indexer option in test

Update CLAUDE.md to require both `docker compose build readmeabook` and a full `npm run test` (0 failures) before reporting work as ready to be tested. Also modify tests/components/admin-settings-indexers.test.tsx to include `indexerOptions.skipUnreleased: true` in the test fixture so the test reflects the skipUnreleased option.
