Module yaml 

YAML parser groundwork for long-term Panache integration.

This module is intentionally minimal and currently acts as a placeholder for a future in-tree YAML parser that can produce Panache-compatible CST structures. Initial goals:

• support plain YAML and hashpipe-prefixed YAML from shared parsing primitives,
• preserve lossless syntax/trivia needed for exact host document ranges,
• enable shadow-mode comparison against the existing YAML engine before rollout.
• prepare for first-class YAML formatting support once parser parity is proven.
