Add "Copy JSON" / "Save JSON" option to row selection export menu in Prisma Studio

Problem

When working with data in Prisma Studio, I often need to copy selected rows in a format I can paste directly into code, API request bodies, config files, or test fixtures. JSON is the most natural format for this, pasting into a JS/TS file, a REST client, or a mock data file all expect JSON, not Markdown tables or CSV.

Currently I have to copy as CSV or Markdown and manually convert it to JSON, which is extra friction for a very common workflow, especially when working with nested/relational data where JSON preserves structure better than a flat table format.

Proposed solution

Add "copy json" and "save json" entries to the existing "copy as" dropdown (see attached screenshot), next to "copy csv" and "save csv".

• Selecting one or more rows and choosing "copy json" would copy the selected rows to the clipboard as a JSON array of objects, with column names as object keys.
• "save json" would download the same output as a .json file.
• The existing "include column header" toggle should not apply to JSON output, since JSON is already self-describing (keys = column names) and there's no equivalent "headerless" concept the way there is for CSV/Markdown. Open to feedback from maintainers if they'd prefer different behavior here (e.g. a headerless array-of-arrays mode).

Alternatives

Currently the only workaround is to copy as CSV or Markdown and convert to JSON manually outside of Studio (e.g. via a script or an online converter), which is slow and disrupts the workflow, especially for quick one-off lookups directly in Studio.
