feat(cli): drop the local wavegrid.json option from init (store-only)

The interactive "Also write a local wavegrid.json here?" prompt was confusing
and duplicative: init already persists everything to the centralized store, so
a second local copy just raised "why two configs?". Remove the prompt and the
local-write path entirely (no flag) so init is purely store-driven. A local
wavegrid.json is still *read* (confstash) for git-checkout workflows if someone
authors one by hand.
