README: tmux requirement wording, invite-only list marker, name
charset, --party on moderation rows, PARTY_SOCKET_DIR whitespace note,
read-only join fallback. deploy.sh: drop phantom tests/run-remote.sh
include (file lives under legacy/ only) and fix the ship-list comment.
SERVERS.md and HISTORY.md were refreshed too but stay local-only per
.git/info/exclude ("Local docs — never published").
tmux-party: share a tmux session with people on the same UNIX host.
Single-file POSIX shell (party) with a filesystem + tmux server-access
trust model. See README.md.
