*Node and Directory are types of the tvix-castore model, not the tvix
DirectoryService model. A DirectoryService only happens to send
Directories.
Move types into individual files in a nodes/ subdirectory, as it's
gotten too cluttered in a single file, and (re-)export all types from
the crate root.
This has the effect that we now cannot poke at private fields directly
from other files inside `crate::directoryservice` (as it's not all in
the same file anymore), but that's a good thing, it now forces us to go
through the proper accessors.
For the same reasons, we currently also need to introduce the `rename`
functions on each *Node directly.
A followup is gonna move the names out of the individual enum kinds, so
we can better represent "unnamed nodes".

This uses our own data type to deal with Directories in the castore model.
It makes some undesired states unrepresentable, removing the need for conversions and checking in various places:
- In the protobuf, blake3 digests could have a wrong length, as proto doesn't know fixed-size fields. We now use `B3Digest`, which makes cloning cheaper, and removes the need to do size-checking everywhere.
- In the protobuf, we had three different lists for `files`, `symlinks` and `directories`. This was mostly a protobuf size optimization, but made interacting with them a bit awkward. This has now been replaced with a list of enums, and convenience iterators to get various nodes, and add new ones.

Make constructing of a new Evaluation use the builder pattern rather
than setting public mutable fields. This is currently a pure
refactor (no functionality has changed) but has a few advantages:
- We've encapsulated the internals of the fields in Evaluation, meaning
we can change them without too much breakage of clients
- We have type safety that prevents us from ever changing the fields of
an Evaluation after it's built (which matters more in a world where we
reuse Evaluations).
More importantly, this paves the road for doing different things with
the construction of an Evaluation - notably, sharing certain things like
the GlobalsMap across subsequent evaluations in eg the REPL.

It being moved outside the PathInfoService trait doesn't prohibit
