Summary by cubic

Upgrade the test-only dependency serial_test in dependi-lsp from 3.5.0 to 4.0.1, pulling in syn v3 and raising the MSRV to Rust 1.93.1. This affects the test suite only; no runtime changes.

• Dependencies

  • Bump serial_test to 4.0.1 and serial_test_derive accordingly, which introduces syn v3.
  • Update dev-dependency in Cargo.toml to serial_test = "4".

• Migration

  • Ensure the Rust toolchain (local and CI) is 1.93.1 or newer for tests.
