fix: optimize proposer boost dependent root check

[nflaig]

An epoch-boundary checkpoint update can stale the cached head before the first block is imported. Recomputing head unconditionally fixes that, but adds a second fork-choice run to the normal import path. The justified checkpoint provides the same dependent root whenever it is at or after the dependent slot, with a fresh-head fallback for exceptional cases.

• Use the justified checkpoint as the proposer boost dependent-root anchor when it proves the canonical root.
• Recompute fork choice only when the justified block is older than the dependent slot.
• Re-enable the affected compliance case.
