Module inferrer 

Pattern inference engine.

This module implements the core algorithm that derives a transformation pattern from one or more before/after example pairs. The process works as follows:

1. Parse both the before and after code into tree-sitter ASTs.
2. Walk the two trees in parallel, performing a structural diff.
3. Where leaf nodes differ (identifiers, literals, etc.), extract them as PatternVars.
4. Where the structure is identical, preserve it verbatim in the template.
5. Assemble the before_template and after_template and compute a confidence score.
