... not just a TODO.
Most use-cases of unsafeDiscardStringContext are for cases where a
string is processed in some ways and no longer contains a "physical"
reference, but still has its context attached in C++ Nix.
We don't need to do this. This does diverge in behaviour in use-cases
related to build scheduling, but that whole behaviour will be
different in Tvix.

It was set to `canon` for `tvl-kit` (not sure if manually, or some
autodetection previously did it for us that's not present anymore).
Anyways, this sets it to how it's set in the web interface, to hopefully

This adds a function that consumes a [proto::node::Node] pointing to the
root of a (store) path, and writes the contents in NAR serialization to
the passed [std::io::Write].
We need this in various places:
- tvix-store's calculate_nar() RPC method needs to render a NAR stream
to get the nar hash, which is necessary to give things imported in
the store a "NAR-based" store path.
- communication with (remote) Nix (via daemon protocol) needs a NAR
representation.
- Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a
NAR representation.

There is a code path in public-inbox that will (under certain
conditions) set the expected list-id as derived from the recipient
mail address (so in our case depot@tvl.su -> `List-ID: depot.tvl.su`).
However, when/how this triggers seems to be particular to the code
path taken based on certain config settings. I couldn't fully figure
it out, and to be honest I don't really know Perl, and I don't think
this warrants a super-high-effort investigation.
For that reason, this patches the appropriate line in
public-inbox-watch to always trigger this code path regardless of what
is going on with the email.
I tested this locally with a public-inbox config that does *not* have
a `listid` setting set, as that just adds an additional filter which
would be a no-op in this case. All emails are ingested correctly with
List-ID set.
There might be a better place to put this in (e.g. right before the
actual mail ingestion), if a Perl expert is interested in figuring
this out and considers it relevant, feel free to send a CL.
Note that this will not update old emails. Probably.
