## Metadata contract
New PNG outputs add two generic `tEXt` chunks:
New outputs expose two generic metadata fields: PNG uses `tEXt` chunks, while JPEG and WebP use XMP properties:
```text
engine = ComfyUI
tools = ["Image MetaHub"]
```
`tools` is a JSON array, not a delimiter-based string. This keeps engine attribution semantically distinct from additional creation, processing, editing, or saving tools. It also survives `ExifReader` independently of which generation parser wins.

The same values are included in `imagemetahub_data` for MetaHub consumers, while the separate chunks are the upstream interchange contract. Existing `parameters`, `workflow`, `prompt`, and `imagemetahub_data` fields are unchanged.
