Rebrand the Rust client crate (coven/ → hh/, package+binary "hack-house"), README, CLI strings, and branch (coven → hack-house). Gitea repo renamed cmd-chat → hack-house to match. Crypto/server logic unchanged; selftest + golden-vector test still green, binary is now `hack-house`. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
