fix(eval): restore any-typing on ai-sdk onStepFinish params for mixed-zod workspace

CI typecheck on the merge commit failed in the eval package: the
onStepFinish destructure inherited from main resolves to implicit-any
under this branch's workspace where the cockpit pins zod v4 and the
server pins zod v3, so the ai-sdk generate() option type widens. Re-
introduce the explicit `any` annotations + biome-ignore comments that
the branch carried before the merge took main's cleaner shape; the
runtime contract is unchanged.

Single-agent.ts: `onStepFinish: async (step: any)` with biome-ignore.
Tool-loop-executor-backend.ts: typed destructure literal with two
biome-ignores on the toolCalls and toolResults any fields.
