The Pi extension conflicted: main gave it the session-id forwarding
doc, this branch had already moved it from `current_exe` to the target
machine's binary. Both kept.
`a_detached_result_lands_after_its_view_is_dropped` now pumps to a
deadline instead of parking once — a `Host` call runs on `HostOps`' own
pool rather than gpui's executor, so there is nothing for
`run_until_parked` to wait on until the answer has already crossed
back.
