* release: v0.0.68

* Fix lint for release: v0.0.68

According to https://github.com/kythe/kythe/blob/master/kythe/typescript/SCHEMA.md#class-declaration static methods should get different vnames from instance methods. But currently static methods are treated as instance methods and vnames overlap. This PR fixes that.

Note that static properties already work correctly.

Many projects using Rust with complicated build systems use
rust-project.json to tell rust-analyzer about their source files. We
can transform rust-project.json into a .kzip pretty trivially, without
needing build system integration. This is simpler than integrating an
extractor into every possible build system which large Rust projects
use.

Add an extractor called rust_project_to_kzip which takes in a
rust-project.json and outputs a .kzip. This kzip will have one
CompilationUnit per Rust crate, and each CompilationUnit will include
a copy of rust-project.json for the Kythe Rust indexer.

This extractor doesn't yet extract non-.rs files or the stdlib.

Test: added unit tests
Fixes #6167

* souffle: fix build with Clang 19

Building souffle with Clang 19 results in the error reported in
this issue:
souffle-lang/souffle#2530

That issue is fixed in a pending pull request to souffle:
souffle-lang/souffle@25ef4de
However, that PR has not yet been merged.

For now, unblock the release by adding a patch to our version of souffle
that does the same thing as the PR.

* fix: fix rapidjson build with Clang 19

We ran into the same issue as the rapidjson devs did in 2016:
Tencent/rapidjson#718

The fix is the same:
yachoor/rapidjson@3b2441b

I would have updated rapidjson, but we are actually on the latest release (from 2016!)

Fixes 6171

The extracted Kythe release archive can now be added as a `bazel_dep` via `local_path_override`. Upon the next release, it could also be added to the Bazel Central Registry.

See
https://github.com/protocolbuffers/protobuf/blob/main/docs/implementing_proto3_presence.md#to-iterate-over-all-oneofs
for more info.

This helps silencing some error within simple proto3 files

```
syntax = "proto3";

package moo;

message Bar {
  ...
  map<int32, int32> foo = 12;
}
```

which would yield
```
file_descriptor_walker.cc:262] Unexpected location vector [] while walking moo.proto
```

before this change.
