add better reading utilities

[luxass]

What is the feature you are proposing?

Currently, the only way to read the lockfile and get it validated is by using a FS Bridge. That makes it a hard dependency on the fs-bridge, which it doesn't need to be!

@copilot Can you take a stab at this?

You can decide how you would implement it. It just needs to be semi runtime agnostic, like the fs bridge is.
