4ac6423b26 refactor(tvix/nar-bridge): Clean up directory popping loop
This change got lost in the rebases in cl/9348. There's unnecessary
`break`/`continues` that can be replaced by moving the conditional into
the for loop condition.

84aa07a736 fix(tvix/nar-bridge): Fix directory stack tracking
Previously, nar-bridge, had a couple of bugs with tracking the current
directory when traversing a NAR file.

The included test case looks like:
```
/ (dir)
/test (dir)
/test/tested (file)
/tested (file)
```

Previously, we would do a string prefix match between the current node
and the top of the directory stack to determine if the node is in the
directory. In this case `/test` is a substring of `/tested`; however,
`/tested` is not in the `/test` directory. The fix is to append a `/` to
the directory name when doing the prefix match, so `/test/` is not a
prefix of `/tested`.

Additionally, when popping the stack, we need to continuously pop the
stack until the new node is in the directory at the top of the stack
(stopping before we pop the root directory)

Example:
```
/ (dir)
/a (dir)
/a/b (dir)
/a/b/c (file)
/z (file)
```

Previously, `z` would end up in directory `/a` because we only the pop
the stack once.

The included test case requires both of these issues to be fixed for it
to pass, so I think it is sufficient.

5841047c38 feat(tvix/nar-bridge): increase timeouts
In some cases, Nix is not able to stream the NAR file fast enough. Bump the
timeouts for now. We might want to get a better understanding in what's
happening here long-term, and/or make the timeouts configurable.

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
