• PRD: ES TradingView-to-Nautilus strategy evolution system #1

What to build

Add the first TradingView Collector path that exports a real Versioned Dataset for ES RTH 5-minute bars. The collector should use TradingView as the data source, produce a dataset directory matching the Versioned Dataset Contract, and record continuous futures and RTH metadata explicitly.

This slice should be demoable by running a collector command or script that writes a reproducible ES RTH 5-minute dataset which passes the contract validator.

Acceptance criteria

• The collector can collect ES continuous futures 5-minute bars from TradingView.
• The exported dataset includes manifest metadata for ES, RTH, 5-minute interval, continuous futures status, roll policy metadata, collection time, and schema version.
• The exported bars are written in the contract format and pass validation.
• RTH handling is explicit in metadata and reflected in exported bars.
• The export path does not require NautilusTrader to run.
• Tests or fixtures verify that a collected or mocked ES dataset is written in the same shape expected by the validator.
