98c17147c6 refactor(tvix/nar-bridge): have Export return root node
… and nar size / sha256 digest.

Instead of producing sparse PathInfo messages when NARs are sent to
nar-bridge, the nar-bridge http server now keeps a lookup table
(narsha256) -> (rootNode, narSize)

This removes a whole bunch of noise, because we don't need to keep
sparse fields around.

A convenience function
`GenPathInfo(rootNode *castorev1pb.Node, narInfo *narinfo.NarInfo)` is
added, which is used to produce PathInfo messages, either when receiving
a NAR file over http and uploading it to a remote PathInfoService, or to
synthesize the PathInfoMessage to return to the client, if nar-bridge is
acting as a PathInfoService for a remove Nix HTTP Binary cache.

9c0d66197b feat(tvix/nar-bridge): do pathInfo.Validate() as additional check
This should make it quite quick to spot writing code breaking some of
the assumptions we have on PathInfo messages ourselves.

We run narInfo.Check to ensure this parses to a StorePath, not
nixpath.Check.

cb807ad79b refactor(tvix/nar-bridge): do root directory dgst check in uploader
This check makes more sense there, and gives stronger semantics - Done()
only succeeds if the other side successfully received everything, *and*
came up with the same hashes as we did.

c04041a001 feat(tvix/nar-bridge): add nar-bridge-pathinfo command
This adds an additional nar-bridge-pathinfo command.

It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.

It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.

It's one building component as soon as we have store composition (which
we currently don't, so don't use this).

It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.
