feat(cli): add mesh templates and claudemesh create command

Predefined mesh configurations (dev-team, research, ops-incident,
simulation, personal) let users bootstrap meshes with groups, roles,
state keys, and system prompt hints. Templates are bundled at build
time via Bun's JSON import support.
