* chore(validator): pin oro-env-runtime 3.3.0 (runtime contract 2)

- Pin oro-env-runtime 3.3.0 in the validator and local-test groups; the
  image smoke check and the local CLI test expect 3.3.0. The lock is
  regenerated once 3.3.0 is on PyPI.
- The compat test fixture words every stock line its situations need
  (3.3.0 takes the shopper's stock lines from the task).
- The bundled local-test pack test also checks the delivery's runtime
  contract, so a contract-1 pack fails here rather than at load.
- Miner guide: how a task with no fitting listing ends (abstain).

* chore(local-test): bundled practice pack for runtime contract 2

Replace the bundled qualifying practice pack with one sealed for runtime
contract 2 (oro-env-runtime 3.3.0): the same 30-row qualifying layout and
catalog/search identity, with the shopper's stock lines in each task. The
pinned digest moves 90169a07 -> f75b76c8 in the CLI test, the local runner
default, docker-compose and the miner guide.
