ci(e2e): nightly-deploy-hardhat cell (Phase 5b) (#89)

- New test-nightly-publish matrix (max-parallel: 1, schedule/dispatch only)
- New nightly-deploy-hardhat cell: full EVM deploy with --no-contract-build
- Fix hardhat fixture: move Lock.json from artifacts/Lock.sol/ (standard
  Hardhat layout) to artifacts/contracts/Lock.sol/ (@parity/hardhat-polkadot
  plugin layout that contracts.ts reads in skip-build mode)
- Report job extended to fan-in test-nightly-publish
- CLAUDE.md: 9 cells across four matrices

+Nightly E2E now exercises the Hardhat (EVM) full-deploy path: a new `nightly-deploy-hardhat` cell publishes the hardhat fixture's pre-built `Lock.sol` bytecode to the `e2e-cli-hardhat.dot` domain on Paseo. Runs on schedule/dispatch only (max-parallel: 1 with `pr-deploy-frontend`/`pr-deploy-foundry` since they share SIGNER), so per-PR runtime is unaffected.
