The analytics, consent, and dsr optional-core generators lacked the
byte-identical reconstruction e2e tests the other five optional cores
already have. Add the three tests and their snapshots.
Adding three more tests exposed a latent flaw in the suite: each test
does a full `pnpm install` in a temp clone, and running all eight in
parallel saturated vitest's workers (RPC timeout) while the never-cleaned
temp dirs filled the disk. Run the suite sequentially via
`fileParallelism: false` and remove each temp clone with `onTestFinished`;
also exclude the local `.pnpm-store` from the clone.
Registers pnpm turbo gen core-package with an empty choices list and a
dispatch table that throws for unknown names. Adds vitest config + test
script to turbo/generators and adds it to the pnpm workspace so tests
run via pnpm --filter @repo/turbo-generators test.
