Assemble the end-to-end capstone pipeline

Stakeholders want a single workflow that fetches weather data on a schedule, normalizes fields, skips duplicates already stored for the day, batches work, validates quality, and splits success from failure — a complete pipeline using every pattern from the course.

You'll build from scratch: a Schedule Trigger, HTTP Request to wttr.in, Code transforms, a Data Table for deduplication, Loop Over Items for batching, an evaluation Code node, and an If node routing to success or failure outcomes.
