Task 10 of the slice plan. parseAiResponse runs the model JSON
through a zod RawResponseSchema, then enforces slice rules:
- title MUST contain Korean characters; throw otherwise.
- summary normalized to exactly 3 lines (pad with empty when too
few; collapse trailing lines into line 3 when too many).
- tags filtered to /^[a-z0-9]+(-[a-z0-9]+)*$/ kebab-case and
capped at 3.
buildPrompt assembles the user-facing prompt with explicit
Korean-output / kebab-tag / no-fence rules (PROMPT_VERSION=1).
Verification: `npx vitest run tests/unit/ai-schema.test.ts`
7 passed.
