Bug Fix: decide() parallelism improvement

decide() now simulates step completions in-memory before computing claimable steps. Previously, successor tasks were invisible until the next vectl_decide round-trip, preventing parallel dispatch of successor + independent tasks.

Before: decide → [complete(A), dispatch(B)] → decide → [dispatch(A_successor)] (2 rounds)
After: decide → [complete(A), dispatch(A_successor), dispatch(B)] (1 round)
