Pull request overview

This PR adjusts the vote/stonks testing and CI flows to handle fork time warps caused by vote enactment, while updating associated on-chain metadata and interfaces for the 2026-08-05 upgrade/test suite.

Changes:

• Split stonks integration CI into “pre-vote” and “post-vote” passes, with a fork restart between them.
• Add a CI utility to refresh the vaults report after vote enactment so core tests don’t fail on VaultReportStale.
• Update 2026-08-05 upgrade metadata/IPFS description inputs, tighten role-holder assertions in the test, and align the TokenRateNotifierV2 ABI + test call sites.
