v0.9.3

Changed

• Dependencies bumped to latest stable — keeps the lib.rs / docs.rs
  badges green. Zero source changes were required:

  • socket2 0.5 → 0.6 — oxvif already used the _v4-suffixed multicast
    methods that 0.6 makes mandatory, so the upgrade is API-compatible.
  • tokio 1.52.0 → 1.52.1 — upstream patch reverting a regression
    that caused spawn_blocking to hang under load.
  • toml 0.8 → 1.1 (dev-dep only, used by the mock_server example
    for state persistence). MSRV requirement (1.85) already met.

  All 420 tests (375 lib + 19 doc + 26 mock server) continue to pass.
