fix(sandcastle): assign opus to actor, sonnet to planner, increase planner iterations

Swap model assignments: claude-opus-4.6 (high effort) for the actor,
claude-sonnet-4.6 (medium effort) for the planner. Increase planner
maxIterations from 1 to 5 so it can actually read AGENTS.md and
project context before producing its analysis.
