If upstream difficulty decreases between workbase updates, downstream miners may submit shares that get rejected.

*Add watch::channel alongside the existing workbase channel, and handle it in the stratifier select loop.

Currently, upstream mining.set_difficulty changes are only applied to downstream miners when the next workbase update arrives. Add a dedicated watch channel for difficulty so stratifiers can react immediately. If upstream difficulty decreases between workbase updates, downstream miners may submit shares that get rejected. *Add watch::channel<Difficulty> alongside the existing workbase channel, and handle it in the stratifier select loop.
