previously, `builtins.break` didn't force its argument, resulting in
a value wrapped with `break` being opaque to most builtins if not
also wrapped with `seq`. see [lix-project/lix#1165] for more details
on what this can break.
this tiny fix just adds a call to `forceValue` inside `prim_break`,
but unfortunately this "breaks" a few existing tests because it
changes the call stack; those tests' golden outputs have been adjusted
without modifying their intended purpose.

- Use a recursive descent parser so that it's easy to extend.
- Add `@args` to enable customizing command-line arguments
- Add `@should-start` to enable `nix repl` tests that error before
entering the REPL
- Make sure to read all stdout output before comparing. This catches
some extra output we were tossing out before!
