Overview

Resolves the on-disk output path for each target format in a multi-format conversion (TODO 72).

Rules:

- One format + path has extension → use the path as-is.
- One format + path has no extension → append ".<format>".
- Many formats + path has extension → +ArgumentError+ (ambiguous).
- Many formats + path has no extension → append ".<format>" per target.

Pure value object: no I/O, no mutation. Extracted from ConvertCommand so multi-format path resolution can be tested independently of the transformation pipeline.
