v0.16.0

Ractor v0.16.0 and ractor_cluster are released!

Since v0.15.13, development has focused on the 0.16 release: adding opt-in ergonomic actor-definition macros and borrowed registry lookups; reducing actor-loop, tracing, process-group shutdown, registry, and cluster-serialization overhead; and fixing factory heartbeat handling. Cluster reliability was strengthened with bounded inbound frames, correct tracing feature gating, deterministic duplicate-session resolution, and the authenticated-callback spelling correction. The release also raises MSRV to Rust 1.85 and modernizes dependencies and CI.
