Summary

• Bump onex_change_control package version to v0.5.3 after the OMN-12765 dev integration promotion landed on main.
• Rebase onto current main so OCC's own in-tree Receipt Gate includes the refreshed OMN-12765 release receipts.
• Refresh the in-tree dod-occ-main-release-pr-2280 receipt to bind to the rebased version bump commit.

Verification

• git diff --check
• pyproject/uv.lock version consistency check
• uv run validate-yaml contracts/OMN-12765.yaml
• uv run python scripts/lint_contract_check_values.py contracts/OMN-12765.yaml
• uv run python -m omnibase_core.validation.validator_occ_merge_eligibility ... => eligible=true, 43 receipts
• uv run pre-commit run --all-files
