- Drop X3DH tests
- Drop cross-version tests with libsignal v0.12 and v0.21
- Change session benchmarks to use PQXDH, which is relevant if doing
comparisons before/after this commit.
`cargo update` performed with Cargo 1.72 to avoid advancing our MSRV. assert_cmd, clap, protobuf, and protobuf-json-mapping needed to be manually held back.
Plus, explicit bumps for
- env_logger 0.11
- heck 0.5
- itertools 0.13
- num_enum 0.7
- prost 0.13
- tungstenite 0.23
And disallowing downgrading curve25519-dalek below the security update in 4.1.3.
By importing past tags of libsignal-protocol, we can check how the
current implementation behaves against previous versions. This initial
test only does v3 (pre-Kyber) 1:1 sessions, but we can add more tests
in the future.
