fix(data): reject non-positive replayed levels

[proerror77]

Change contract

Reject a Binance market-tape Verified handle when any final replayed bid or ask level has a non-positive price or quantity.

Out of scope

• Aggregate-trade completeness (merged separately in fix(data): require trades for every tape symbol #128)
• First-segment snapshot seeding (merged separately in fix(data): require first-segment snapshot seeds #129)
• Rejecting zero-quantity diff deletion events before replay
• Timeline projections, PIT materialization, collector, uploader, or deployment changes

Dependency / merge order

None. This PR was originally stacked on #129; after #129 merged it was retargeted to main, updated, and revalidated at exact head cf0c3ac4152936a6a1b5a7b3aeef34ffecdb78f4.

Focused validation

• Review budget: 1 changed file, +23/-0, below the 25-file / 750-line split threshold.
• Red GitHub/Linux counterexample: run 29638627699 failed only non_positive_replayed_book_levels_never_return_a_verified_handle; the old verifier incorrectly returned a verified handle with a zero price or negative quantity in the final ask.
• Green GitHub/Linux implementation run 29639050482 passed rustfmt and all focused verifier tests before the base update.
• Exact-head GitHub/Linux focused run 29639171291 passed rustfmt and all verifier tests for cf0c3ac4152936a6a1b5a7b3aeef34ffecdb78f4.
• Exact-head standard CI run 29639139992 passed Rust Workspace, Rust HFT Engine Fast Lane, production image/Kubernetes contract, and the repository security lanes.
• Safety boundary preserved: zero-quantity diff deletion remains legal because validation applies only to the completed replayed book.

Rollout / rollback impact

Verifier-only fail-closed tightening. No runtime service changes. Rollback is reverting this PR; artifacts with non-positive final levels remain rejected while active.

Warning

Review limit reached

@proerror77, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 27 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.
