🧠 AI Summarization

Powered by the blazing-fast DeepSeek R1 API.

• Summary generation is triggered via a Summarize button on each note.
• The summarizeNote server action sends note content to the DeepSeek R1 API.
• Responses are parsed with full TypeScript safety and fallback error handling.
• Toast messages via sonner display feedback for success, rate-limits, or unknown errors.
• Server error parsing uses strict unknown type narrowing for clean logs and lint-free code.
