add trace viewer support

Adds a Pi-compatible JSONL export so the conversation, reasoning, and tool call can be browsed in the Hub trace viewer. Adds a short README note linking to the raw Parquet data and updates the reproduction script to load it directly.

 # Qwen 3.8 Flash Next Investigation
 
 This dataset contains the model trace and corresponding raw token IDs from the behaviour observed in https://cohere.com/blog/concerning-behaviour-popular-open-weight-ai-model

+The trace viewer uses a Pi-compatible JSONL export of the original conversation. Its timestamps record export time, and the original system prompt is preserved as a displayed custom message with its original role recorded in metadata. The Parquet contains the original trace and token IDs.

 # Reproduction
 
 Below we provide a script for reproducing the unexpected behaviour.
