feat(M1): TCP/TLS control plane -- auth, channels, ephemeral text

Implements the full M1 milestone. Two clients authenticate over TLS 1.3 (guest + Argon2id password) and exchange channel + private text messages through a real server. All five ctest --preset m1-dev tests pass in ~1 s. Key components added: - vcpkg baseline + m1-dev preset (protobuf/mbedTLS/libsodium/asio/sqlite3) - FrameCodec feed+emit, encode/decode_envelope, protobuf codegen - TcpServerConn with blocking TLS handshake thread + tls_read_loop - TlsContext (mbedTLS 1.3, ECDSA-P256 self-signed cert, TOFU on client) - WorkerPool (3 threads, used for Argon2id) - Database: SQLite + libsodium Argon2id, account lifecycle, bootstrap admin - ServerIdentityManager: Ed25519 key + cert generate/persist/fingerprint - ConnSession state machine: WaitingHello -> WaitingAuth -> Authenticated - SessionRegistry: channel tree, user map, text routing, broadcast - vc_client full M1 C ABI: connect/TLS/handshake/auth/text/disconnect - voicecat-admin CLI: account add/reset/del/list - test_m1_integration: M1 exit criterion, verified green Bug fixed: double-framing in ConnSession::send_envelope -- encode_envelope was adding the [4-byte len] prefix, then TcpServerConn::send_frame added a second one, causing the client to parse [len][proto] as protobuf (silent failure). Fixed by serializing raw protobuf bytes in send_envelope and letting send_frame apply the single length prefix. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
