- measure_mls_wire_sizes: KeyPackage, Welcome, Commit, AppMessage sizes
- measure_mls_wire_sizes_hybrid: same with post-quantum mode
- measure_mesh_envelope_overhead: MeshEnvelope overhead for various payloads
These tests print actual byte sizes to inform constrained link
feasibility planning (LoRa SF12, MLS-Lite design).
Migrates all MLS code in quicprochat-core from OpenMLS 0.5 to 0.8:
- StorageProvider replaces OpenMlsKeyStore (keystore.rs full rewrite)
- HybridCryptoProvider updated for new OpenMlsProvider trait
- Group operations updated for new API signatures
- MLS state persistence via MemoryStorage serialization
- tls_codec 0.3 → 0.4, openmls_traits/rust_crypto 0.2 → 0.5
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.
