feat: use mb-stack

[Dodecahedr0x]

Summary by CodeRabbit

• Bug Fixes

  • Improved test reliability for local and remote environments by handling wallet setup and funding more safely.
  • Made authenticated connections more tolerant of missing auth tokens.

• Chores

  • Simplified local test startup by using a single stack process and added clearer readiness checks and failure logs.
  • Streamlined cleanup so local test runs shut down more consistently.

Warning

Review limit reached

@Dodecahedr0x, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 53 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

This PR updates the Pinocchio private-counter test to conditionally generate and fund an ephemeral keypair for local runs, tolerate missing TEE auth tokens, and refactors test-locally.sh to start and manage a single supervised mb-stack process instead of separate validator/service processes.

Changes

Private-counter local test funding

Layer / File(s)	Summary
Local vs remote keypair and TEE token handling private-counter/pinocchio/tests/pinocchio-private-counter.test.ts	Adds isLocal detection derived from PROVIDER_ENDPOINT to generate a fresh keypair locally (funded via airdrop in beforeAll) or load from PRIVATE_KEY/default file otherwise; uses optional chaining for the unauthorized TEE auth token when building connection URLs.

Estimated code review effort: 3 (Moderate) | ~20 minutes

mb-stack orchestration refactor

Layer / File(s)	Summary
mb-stack startup, readiness polling, and cleanup scripts/test-locally.sh	Replaces individual mb-test-validator, ephemeral-validator, and QFS startup with a single mb-stack process tracked via MB_STACK_PID, polling mb-stack.log for readiness with timeout/error handling, and updating cleanup() to terminate the stack via SIGTERM/SIGKILL.

Estimated code review effort: 3 (Moderate) | ~20 minutes

In `@private-counter/pinocchio/tests/pinocchio-private-counter.test.ts`:
- Around line 55-62: The local keypair setup eagerly reads the fallback file
before the isLocal branch is applied, so local runs can still crash in the test
setup. Update the userKeypair initialization in
pinocchio-private-counter.test.ts so the fs.readFileSync call only happens in
the non-local path, and keep Keypair.generate() as the only path used when
isLocal is true; use the existing isLocal, KEYPAIR, and userKeypair symbols to
locate the fix.
