Don't use DirectoryError, but PathComponentError.
Also add checks for too long path components.

Replace the hand-rolled code comparing names with a try_fold. Also, make
it slightly stricter here, detecting duplicates in the same fields
earlier.

This encodes a verified component on the type level. Internally, it
contains a bytes::Bytes.
The castore Path/PathBuf component() and file_name() methods now
return this type, the old ones returning bytes were renamed to
component_bytes() and component_file_name() respectively.
We can drop the directory_reject_invalid_name test - it's not possible
anymore to pass an invalid name to Directories::add.
Invalid names in the Directory proto are still being tested to be
rejected in the validate_invalid_names tests.

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.

*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.

This adds `Directory::add` which is a convenience helper for adding
nodes into a `Directory` while preserving sorted order.
This implements `Ord` and `PartialOrd` for `FileNode`, `SymlinkNode`,
and `DirectoryNode` so `binary_search` can be used.

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

Implement `validate()` on `node::Node`, and call it from PathInfo's
validate() too. Node-related errors are moved to a ValidateNodeError
error type.
This additionally adds some more validations for symlink targets (they
must not be empty, and not contain null bytes).

We use checked arithmetic for computing the total size, and verify
that size is in-bounds in Directory::validate.
If an out-of-bounds size makes it to the "unchecked" size method,
we either panic (in debug mode), or silently saturate to u32::MAX.
No new panic sites are added, since overflows in debug mode already
panic at the language level.

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)
