Nodes only have names if they're contained inside a Directory, or if
they're a root node and have something else possibly giving them a name
externally.
This removes all `name` fields in the three different Nodes, and instead
maintains it inside a BTreeMap inside the Directory.
It also removes the NamedNode trait (they don't have a get_name()), as
well as Node::rename(self, name), and all [Partial]Ord implementations
for Node (as they don't have names to use for sorting).
The `nodes()`, `directories()`, `files()` iterators inside a `Directory`
now return a tuple of Name and Node, as does the RootNodesProvider.
The different {Directory,File,Symlink}Node struct constructors got
simpler, and the {Directory,File}Node ones became infallible - as
there's no more possibility to represent invalid state.
The proto structs stayed the same - there's now from_name_and_node and
into_name_and_node to convert back and forth between the two `Node`
structs.
Some further cleanups:
The error types for Node validation were renamed. Everything related to
names is now in the DirectoryError (not yet happy about the naming)
There's some leftover cleanups to do:
- There should be a from_(sorted_)iter and into_iter in Directory, so
we can construct and deconstruct in one go.
That should also enable us to implement conversions from and to the
proto representation that moves, rather than clones.
- The BuildRequest and PathInfo structs are still proto-based, so we
still do a bunch of conversions back and forth there (and have some
ugly expect there). There's not much point for error handling here,
this will be moved to stricter types in a followup CL.

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.

ClosureValidator was previously only suitable for a very narrow use case:
Validating incoming uploads, which are in leaves-to-root order.
This is because the ordering validation was hard-wired into the add()
function.
This
- Re-name ClosureValidator to DirectoryGraph, which is more suitable
since it actually stores the Directory structs and is drained in the end.
- Move the ordering-related logic to a separate OrderValidator, which
can be used independently.
- re-write DirectoryGraph to be a general purpose
validator which can accept the input in both orders
and can be drained in both orders as well.
This means the DirectoryGraph and OrderValidator can now serve
multiple new purposes:
- Validating the incoming closure on the client while downloading.
- Validating the incoming closure downloaded in a caching layer from the
`far` cache, and re-order it for insertion into the `near` cache.

We can just use the `BoxStream` directly, or a `once` with the single
`Directory`.
In the recursive case, we also did not properly close the channel after
the first error.

This greatly simplifies the code in this function, replacing it with a
much better tested (and more capable!) version of the validation logic.
It also enables the gRPC server frontend to make use of the
DirectoryPutter interface. While this might not be too visible in terms
of latency thanks to gRPC streams bursting, it also enables further
optimizations later (such as bucketing of directory closures).

This only contains the outer metadata wrapping, and that's not too interesting:
> Request { metadata: MetadataMap { headers: {"content-type":
> "application/grpc", "user-agent": "grpc-go/1.60.1", "te": "trailers",
> "grpc-accept-encoding": "gzip"} }, message: Streaming, extensions:
> Extensions }
Drop these fields for now, and rely on the underlying implementations to
add instrumentation for the application-specific fields.
Clean up the error logging a bit.

We can also drop the Clone requirement. Because the trait is async since
some time, there's no need to clone before moving into an async closure,
allowing us to simplify the code a bit.

Having more than 4GiB files is quite possible (think about the NixOS
graphical installer, and an uncompressed iso of it).
No wire format changes.

This splits the pure content-addressed layers from tvix-store into a
`castore` crate, and only leaves PathInfo related things, as well as the
CLI entrypoint in the tvix-store crate.
Notable changes:
- `fixtures` and `utils` had to be moved out of the `test` cfg, so they
can be imported from tvix-store.
- Some ad-hoc fixtures in the test were moved to proper fixtures in the
same step.
- The protos are now created by a (more static) recipe in the protos/
directory.
The (now two) golang targets are commented out, as it's not possible to
update them properly in the same CL. This will be done by a followup CL
once this is merged (and whitby deployed)
