Commit Message

Fix sandboxer daemon inheriting parent stdin/stdout file descriptors (#23246)

Redirect the sandboxer daemon's stdin and stdout to `/dev/null` when
spawning, preventing it from holding the parent's file descriptors open
indefinitely

When the sandboxer daemon is spawned without explicit stdin/stdout
configuration, it inherits the parent's file descriptors. If those FDs
are pipes (e.g., `pants ... | grep`, pre-commit hooks, IDE integrations,
AI coding tools capturing output) or regular files, the sandboxer holds
them open for its lifetime, preventing EOF and causing the caller to
hang.

The sandboxer communicates exclusively via a Unix domain
socket and never reads stdin or writes stdout. All logging
goes to stderr via `env_logger`. This change matches the
existing pattern used by other process runners in the codebase.

Fixes #23169
