feat: send task logs to spaces (#6419)
### Description
Start sending task summaries to spaces. As expected this ended up
touching a few parts of the codebase and required some reworking of
them.
I highly recommend reviewing each commit in the PR individually as I
attempted to keep each one fairly small to make this easier to review.
### Testing Instructions
Observe the runs sent via the Rust codepath from my machine (you can
tell it's Rust based on the `command` 😉 )
