Title: YellowGovernor

Protocol parameter administration for the Yellow Network. Collateral weight is derived from YELLOW tokens posted as security deposits in the NodeRegistry by active node operators. Proposals are queued through a TimelockController before execution. Enforces a minimum quorum floor so quorum never drops below a meaningful absolute value even if total locked collateral shrinks. Includes late-quorum protection to prevent last-minute manipulation of outcomes without giving other operators time to react. A proposal guardian (Foundation multisig) can cancel any proposal as an emergency brake; removable via parameter administration.
