Need to figure out what this means for Windows before ready for review.

I'd like to understand why Ctrl-C isn't working in #10952 but works in other cases, but... it seems generally correct to forward a SIGINT if we've received it multiple times (as an escape hatch).

Keeping this separate for review purposes.

There should be two functional changes here: - If we receive SIGINT twice, forward it to the child process - If the `uv run` child process changes its PGID, then forward SIGINT Previously, we never forwarded SIGINT to a child process. Instead, we relied on shell to do so. On Windows, we still do nothing but eat the Ctrl-C events we receive. I cannot see an easy way to send them to the child. The motivation for these changes should be explained in the comments. Closes #10952 (in which Ray changes its PGID) Replaces the (much simpler) #10989 with a more comprehensive approach. See #6738 (comment) for some previous context.
