dfb48dcade fix(tvix/nar-bridge): drop pathinfoservice
This now exists in tvix-store directly, as NixHTTPPathInfoService, and
contrary to this version, also validates signatures.

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.

8239f32b62 refactor(tvix/nar-bridge): mv nar-bridge{,-http}
Rename the nar-bridge CLI to nar-bridge-http, because it's the one
spinning up an http server.

Defaulting to where `tvix-store daemon` listens to is a sane choice.

0ecd10bf30 feat(tvix/nar-bridge): init
This provides a Nix HTTP Binary Cache interface in front of a tvix-store
that's reachable via gRPC.

TODOs:

 - remove import command, move serve up to toplevel. We have nix-copy-
   closure and tvix-store commands.
 - loop into CI. We should be able to fetch the protos as a third-party
   dependency.
 - Check if we can test nar-bridge slightly easier in an integration
   test.
 - Ensure we support connecting to unix sockets and grpc+http at least,
   using the same syntax as tvix-store.
 - Don't buffer the entire blob when rendering NAR
