JSON output: does it expose the full declaration range? (building a CI/removal helper on top)

[nenadvulic]

I'm putting together a small helper on top of Periphery, mostly CI ergonomics (only flagging the dead code a PR actually introduces) and, if it turns out doable, removing the unused declarations automatically with SwiftSyntax. A few things I wanted to check before going further.

Does the JSON output include the full source range of a declaration, or just the line/column of its name? For the removal part I need to know where the whole declaration starts and ends so I can cut it out cleanly and map it to a SwiftSyntax node. If it's only the name location right now, would you be open to a PR that adds the full range?

Also, is removing code something you'd ever want Periphery to do itself, or do you prefer to keep it detection-only? I don't want to push something against the grain — if it's out of scope that's totally fine, I'll just keep it in my own tool.

Last one, for CI: is there a good way to get only the results introduced against a base branch, instead of the whole --baseline file? Or is that meant to live in a wrapper?

Thanks for the tool, by the way.
