Adds a "Spawning new sessions (no wizard)" section to the bundled
claudemesh skill. Documents every flag of `claudemesh launch`
(--name, --mesh, --join, --groups, --role, --message-mode,
--system-prompt, --resume, --continue, -y, -q, plus -- pass-through),
shows wizard-free spawn templates from minimal to cold-start-with-
join, and the canonical pane-creation primitives (tmux send-keys,
iTerm2 osascript, Terminal.app, gnome-terminal, screen) that wrap
the verb when spawning into a fresh terminal pane or window.
Closes the gap where Claude knew the verb existed but had no
playbook for "how do I start another peer in a new pane without an
interactive prompt firing." Bumps CLI to 1.9.4 so the skill ships
on `claudemesh install`.
