test(cli): pass --provider explicitly in schedule create test

Commit d3f9655e removed the implicit 'claude' default for --provider on
schedule create. Test 1 still relied on the default, which fails fast
with MISSING_PROVIDER. Pass --provider claude so the assertion path that
expects target=new-agent:claude continues to hold.
