Certify the policyengine.py 6.9.0 replay results

This PR commits the receiver's sealed qualification of pe6.9.0_uk2.130.1_policyengine-uk-data-1.58.1, with its release diff against pe6.5.0_uk2.130.1_policyengine-uk-data-1.58.1. The results workflow (.github/workflows/uk-replay-results.yml) built it from the committed receipt, as #188 and #190 were built by hand. Merging stays on the normal gates: CI and an independent review.

What changes

• results/uk/replays/pe6.9.0_uk2.130.1_policyengine-uk-data-1.58.1/ and results/uk/replays/diffs/pe6.5.0_uk2.130.1_policyengine-uk-data-1.58.1__pe6.9.0_uk2.130.1_policyengine-uk-data-1.58.1/: the receiver's requests/705e2b7a…/results/ tree, byte for byte: 231 files, 39.0 MB of aggregate outputs and release-diff packets.
• docs/uk_replay/requirements/pe6.9.0_uk2.130.1_policyengine-uk-data-1.58.1.txt: the variant's requirements freeze.
• data/uk/replay_variants.json: the variant record, the qualification's VARIANT.json exactly plus a note, in canonical form. CI's replay-engine matrix lists the index's certified variants, so it replays this one too; no workflow changes.
• tests/test_uk_replay_qualify.py and tests/test_uk_replay_determinism.py (NEWEST) and tests/test_uk_replay_variants.py (COMMITTED): the tests that name the newest certified variant move to it.
• docs/uk_replay/RELEASE_REPLAY.md: a "Committed certified results" paragraph from the receipt's counts.

Validation in the results run

• The receiver's output guard, applied again to the request's tree: every file an allowed, parsable aggregate.
• Byte identity: all 231 committed result files have the blob replay-state holds; the receipt and results are unchanged since the receipt commit.
• uk_replay_qualify verify-sealed: 3 sealed namespace(s) checked.
• CI's .github/scripts/uk_replay_regenerate.sh leaves the tree unchanged.
• scorecard_db.build_db: two builds agree (3ebf8a86…), and there is no tracked-file drift.

The table and the RELEASE_REPLAY.md paragraph state counts only. Reviewers add any interpretation of flagged rows.

axiom: n/a: replay results and the variant index; no policy encoding.

Merged by squash at head 54c0d004.

• Review. The Opus 5.5 stack review rebuilt this PR offline for request 705e2b7a on post-stack main and judged it MERGE-SAFE (~/reviews/budget-coordinator/scorecard-results-stack/review-out-opus.md, sim/rebuild206.sh). This bot commit has the same git patch-id --stable as that rebuild (e4610529). GPT-6.1 Sol rated the 6.9.0 results MERGE-SAFE with the stack in.
• Gates. gh pr checks exits 0, including the new 6.9.0 replay-engine leg. The PR is MERGEABLE, ready, on base main, with no changes requested.
• 6.9.0 alone. It is on main without 6.6.0–6.8.0: those releases qualified on the same engine pair with 0 flagged rows against 6.5.0, and the builder refuses older releases once a newer one is certified. Certify the policyengine.py 6.7.5 replay results #195 and Certify the policyengine.py 6.8.0 replay results #204 explain this in their close comments.

6.10.0 (Microcosm) has not qualified yet. Both attempts lost the runner at the same AB2025 step. A follow-up measures memory before changing the worker count.
