eda5d4da37 feat(tvix/store): From<&nix_compat::...::NarInfo<'_>> for PathInfo
This allows converting from the NarInfo falling out of the NarInfo
parser (which is a bit annoying to handle due to lifetimes) to the
PathInfo proto struct.

The narinfo field, containing most of the data from the original
NARInfo file, as well as the references (bytes) are populated.
The node field is not populated, because it requires ingesting the NAR
itself to describe the root node.

e32c2070e4 refactor(tvix/nix-compat): no impl <StorePathRef<'_>> for StorePath
This suggests it's cheap to convert around, but name actually does
allocate.

Move to a `to_owned(&self) -> StorePath`, to better signal that this
does allocate.

We don't gain much from making this part of the trait, it's still up to
`tvix_store::pathinfoservice::from_addr` to do most of the construction.

Move it out of the trait and into the specific *Service impls directly.

This allows further refactorings in followup CLs.

327548d2fd refactor(tvix/nix-compat): check presence with btree_map's entry API
Walking a btree_map twice is more expensive than copying a string,
especially because the cloning only happens in the (non-hot) error
path.

This fixes a clippy lint, so it's related to b/321.

67999f0dcf feat(tvix/castore): extend blobstore protos for verified streaming
This pdates the proto docstrings a bit, especially w.r.t. verified
streaming.
It also adds send_chunks, send_bao fields to StatBlobRequest (renamed
from BlobMeta)

b921e3a7e3 fix(tvix/*store-go): fix depot checks
This wasn't doing anything, because $(regenerate) was a directory:

cbd72b56b2 feat(tvix/store/nar): add read_nar method
This adds a function that can ingest a NAR file into a given
blob_service and directory_service, returning the root node.

Passing around the directory_putter is a bit annoying, but at least for
this linear "reading through a NAR" case, we don't need it to be clone
or sync.
