Module shape 

Structural shape classifier for tool responses.

Ports the classifier from docs/research/scripts/extract_paper2_format_events.py into Rust. Keep the two in sync so offline analyses and online decisions share the same taxonomy.

Shape is detected by a two-step rule:

1. If the content parses as JSON, classify by JSON structure.
2. Otherwise, scan the text for markdown / code / numbered-list patterns.
