split(#4502 PR-2): ONT-10 rest — everything in #4502 outside the contracts layer (stacked on #4587)

[noahgift]

Split PR-2 of 2 of #4502 (operator plan: the split is a MOVE of #4502). Stacked on #4587 (base split/pvl-rows-0.70). Once #4587 merges, this PR retargets to main.

What: the full #4502 r7 A 0be7c00372 tree minus PR-1, plus fb's integ fixes (rows 4, 7, 10, 13; row 8 superseded by PR-1's full regen) and the #4445 AC test (forget_prefix_makes_the_same_prompt_prefill_whole_again, 3 turns).

Coverage: fb's union check PASS, PR-1 e13e9eb ∪ PR-2 = #4502 with 0 missing and 0 extra (handoff 4502-union-receipt-postcut).

Generated files: taken from PR-1's batch_fold.sh --regen (census n_files 1889; README CONTRACT_COUNT 1889, check_readme_claims.sh rc0). ontology.ofn, tbox-report.json, discharge-summary.json and Axioms.lean are not included (98 is the single writer).

Pre-push receipts: intel at 78bd48d: cargo fmt --all --check rc0, cargo check --workspace --all-targets --locked rc0. 66's guard-tree on intel: 59 PASS, and all 6 merge-ref guards rc0.

Once #4587 and this PR merge, #4502 closes with links.
