Adds the marianobarrios:tls-channel:1.0.0 dependency (thin ByteChannel-over- SSLEngine wrapper, MIT, zero transitive deps, Java 8 bytecode) and a TlsContextFactory that builds server (keystore) and client (pinned truststore) SSLContexts, TLS 1.3 only. No transport wiring yet — this just compiles in the building blocks for full-session encryption of the Presents NIO stream.
