When (re)initializing a chunked reader, we were erroneously skipping the
first n bytes from all chunks, not just the first one.
Fix this, by passing in an enumerated list of chunks, and only calling
SeekFrom::Start() on the first chunk in the stream.
With this, I'm able to invoke b3sum on bin/bash successfully.

Use a proper graph library to ensure all nodes are reachable from the
root.
We had a bit of that handrolled during add(), as well as later, which
had an annoying bug:
Redundant nodes were omitted during insert, but when returning the list
during finalize, we did not properly account they need to be introduced
before their parents are sent.
We now simply populate a petgraph DiGraph during insert (skipping
inserting nodes we already saw), and use petgraph's DfsPostOrder to
traverse the graph during finalize.
If the number of returned indices equals the total number of nodes in
the graph, all nodes are reachable from the root, we can consume the
graph and return the nodes as a vec, in the same order as the traversal
(and insertion).
Providing a regression test for the initial bug is challenging, as the
current code uses a bunch of HashSets. I manually tested ingesting a
full NixOS closure using this mechanism (via gRPC, which exposes this
problem, as it validates twice), and it now works.

This can be used to validate a Directory closure (connected DAG of
Directories), and their insertion order.
Directories need to be inserted (via `add`), in an order from the leaves
to the root. During insertion, we validate as much as we can at that
time:
- individual validation of Directory messages
- validation of insertion order (no upload of not-yet-known Directories)
- validation of size fields of referred Directories
Internally it keeps all received Directories (and their sizes) in a HashMap,
keyed by digest.
Once all Directories have been inserted, a drain() function can be
called to get a (deduplicated and) validated list of directories, in
from-leaves-to-root order (to be stored somewhere).
While assembling that list, a check for graph connectivity is performed
too, to ensure there's no separate components being sent (and only one
root).
It adds a test suite for these cases, which is much nicer to test than
where we previously had these checks (only in the gRPC server wrapper).
Followup CLs will move the existing putters to use this.

Whenever this encounters an open_read(), it'll first check for more
granular chunking. If there's more granular chunking data available, a
ChunkedReader is constructed (which supports seeking backwards).
This currently is still a bit stupid, and doesn't compose, as
`ChunkedReader` uses `self` as the `BlobService` to ask for the
individual chunks.
In store composition future, we might want to compose this differently,
essentially constructing `ChunkedReader` with another `BlobService`
representing the entire hierarchy, so there's a chance to locally cache
things, and do less requests.

`build.rs` emits rerun-if-changed statements for all proto files, as
well as all include paths we pass it.
Unfortunately, due to protobufs include path rules, we need to specify
the path to the depot root itself as an include path, at least when
building impurely with `cargo`. This causes cargo to essentially always
rebuild, as it also puts its own temporary files in there.
Unfortunately, tonic-build does not chase down to individual .proto
files that are included.
Disable emitting these `rerun-if-changed` statements for now.
This could cause cargo to not rebuild protos every time, causing stale
data until the next local `cargo clean`, but considering the protos
change not that frequently, and it'll immediately surface if trying to
build via Nix (either locally or in CI), it's a good-enough compromise.

The public-consumable thing here is ChunkedReader, not ChunkedBlob.
ChunkedBlob is a helper that can be used to get a new AsyncRead, but
not AsyncSeek. It is used internally by ChunkedReader whenever the
client seeks.
Make this more obvious, by extending the documentation, and putting
ChunkedReader at the top of this file.
Also make ChunkedBlob and its methods private, and give ChunkedReader a
more useful constructor (from_chunks, instead of from_chunked_blob).

Some implementations of DirectoryService might not allow retrieval of
intermediate Directory nodes, that are not at the "root".
Think about an object store implementation. The client is doing a
get_recursive anyways to reduce the number of roundtrips.
By documenting the fact we don't need to support looking up intermediate
Directory messages, we can just batch all directories into the same
object, keyed by the root.

There's no support for verified streaming in here yet, this simply
produces a stream of readers for each chunk, skipping irrelevant chunks
and data from the first chunk at the beginning.
A seek simply does produce a new reader using the same process.

docs/verified-streaming.md explained how CDC and verified streaming can
work together, but didn't really highlight enough how chunking in
general also helps with seeking.
In addition, a lot of the thoughts w.r.t. the BlobStore protocol, both
gRPC and Rust traits, as well as why there's no support for seeking
directly in gRPC, as well as how clients should behave w.r.t. chunked
fetching was missing, or mixed together with the verified streaming
bits.
While there is no verified streaming version yet, a chunked one is
coming soon, and documenting this a bit better is gonna make it easier
to understand, as well as provide some lookout on where this is heading.
