refactor(cli): add nerve create command, remove init workflow

- Add top-level `nerve create` with `workflow` and `sense` subcommands
- Move workflow scaffold from `init workflow` to `nerve create workflow`
- Add `nerve create sense <name>` to scaffold sense boilerplate
- Keep `nerve init` for workspace initialization only
- Add tests for create workflow, create sense, and e2e
