fix: address review — step 1 title misleading, remove redundant disinto up (#684)

- Rename step 1 from "Clone and start the stack" to "Clone disinto"
- Remove bin/disinto up from step 2 snippet (init already starts the stack)
- Clarify that disinto init handles the full bootstrap including stack start
- Note disinto up/down as available for subsequent restarts
