Walkthrough

This PR updates TypeScript type annotations in the guardrails normalization logic within normalizePlanItem and specOutputToPlan functions, adding explicit return types and typed filter predicates for narrowing to GuardrailItem. No behavioral changes.

Changes

Guardrail Typing Annotations

Layer / File(s)	Summary
Explicit guardrail type narrowing app/(main)/task/[taskId]/spec/page.tsx	Both normalizePlanItem and specOutputToPlan annotate the guardrails .map(...) callback as returning GuardrailItem | null and use an explicit typed predicate in .filter(...) to narrow to GuardrailItem.

Poem

Types so sharp, no null shall pass,
Guardrails narrowed, clear as glass,
A rabbit hops through code so neat,
Predicates typed, the fix complete,
Hop, hop, hooray for TypeScript treat! 🐰
