chore: quiet warnings on turborepo build (#6033)
### Description
PR to hopefully make the turborepo build far less noisey:
- Allow dead code in the `turborepo-lib` crate. This is a temporary
measure until we finish the port as we have many components in the
codebase that haven't been hooked up
- Fix clippy warning in daemon (cloning a reference to a type that
doesn't implement `Clone` is just copying the reference)
- Allowing dead code on a private `todo` method. (@NicholasLYang Should
I just remove this?)
### Testing Instructions
Hopefully far less annotations on this PR from warnings during build.
Closes TURBO-1364
