Feature Request: Copy select query to pasteboard

This would help to get the nice query I just build into something else.

This might also be a nice combination with something like: Edit this Query in Terminal, which would use the current query and pre fill the Terminal with it.

The issue names no files, tests, or entry points. Start by locating the query editor and existing pasteboard or Terminal integration, then clarify the expected copied query format and whether Terminal prefill is part of the work; done means the built query can be copied for use elsewhere.
