chore: rename quicproquo → quicprochat in Rust workspace

Rename all crate directories, package names, binary names, proto
package/module paths, ALPN strings, env var prefixes, config filenames,
mDNS service names, and plugin ABI symbols from quicproquo/qpq to
quicprochat/qpc.

+//! Protocol types for quicprochat.
+//!
+//! This crate contains both:
+//! - **v1 (legacy)**: Cap'n Proto generated types from `schemas/*.capnp`
+//! - **v2**: Protobuf generated types from `proto/qpc/v1/*.proto`
+//!
+//! # Design constraints
+//!
+//! - **No crypto** — key material never enters this crate.
+//! - **No I/O** — callers own transport; this crate only converts bytes <-> types.
+//! - **No async** — pure synchronous data-layer code.
