this will become a proper specialization of `nlohmann::basic_json` soon.
specialing basic_json will let us get rid of our `adl_serializer` hacks,
and it'll open the door to better enum serializing behavior without also
forcing all those who use lix as a library to set certain defines (which
may not even be possible depending on how those users use json already).

clangd broke because it can't look through symlinks. compile_commands
manipulation does not fix it, clangd configuration does not fix it, a
vfs overlay does not fix it, and while a combination of those can fix
it with a bind mount in place that's just too cursed to even consider
