We often see `uv` hanging at this line https://github.com/astral-sh/uv/blob/d178e453684437889a30b3ffd17e56d695fba60d/crates/uv-fs/src/lib.rs#L677-L680 . By enabling debug output, we can hopefully see where the lock was acquired before.

## Description Prior to this PR, `run_build_command` contains wrong implementation which calls `cmd.spawn()` and `cmd.status()` sequentially, and since both invocations execute the command, each build command is **executed twice**. The issue is uncovered during my investigation of issue #1090 . This PR addresses the issue by replacing `cmd.status()` with `child.wait()`. Additionally, it also changes the process backend from `std` to `tokio` to improve concurrency. Since the issue has been resolved, #1137 is reverted to reduce verbosity of CI logs. ## Related Fixes #1090
