Prepares the openadapt-flow 2.7.1 release. Merging publishes Flow through release-package.yml.

• Version 2.7.1 in pyproject.toml, openadapt_flow/__init__.py and uv.lock (version line only, as in chore(release): prepare Flow 2.7.0 (do not merge until founder approves) #2123).
• CHANGELOG: ## Unreleased becomes ## v2.7.1 (2026-11-09). The main fix is qualification: reproduce certifications sealed before a reviewed additive field #2134: programs certified before Nov 8 load again under the reviewed sealed-omission rule, and a changed program is still refused. Adds entries for Make ledger settlement atomic and bind rechecks to receipt context #2044 (atomic ledger settlement, receipt-bound rechecks) and test(flow): import-layer checker reads literal dynamic imports and lazy tables #1924 (scaffold-verifier --prove needs a caller-supplied proof source). The existing benchmark: zero-config verifiers vs hand-written under planted faults #2127 entry stays.
• llms-full.txt regenerated.

Tests: flow release and changelog tests (160 passed), root test_release_plan, test_release_lock and related release tests pass; ruff clean.

Retriggering CI now that #1956 turned main green.

Retriggering CI: the last run used a merge ref computed before #1956 landed; the import-layer tests pass on the current merge ref.
