fix(init): tighten stale-step detection and show reconnecting feedback

Two review recommendations from /review:

1. Tighten isStepAlreadyAdvancedError to match "was not suspended" instead
   of "not suspended" — both Mastra error variants use the more specific
   phrase, which reduces the false-positive surface area.

2. Show "Reconnecting..." spinner message before the runById recovery call
   so the user sees feedback during a potentially slow state fetch instead
   of watching a stale spinner message. Passes spin through ResumeRetryArgs
   to give resumeWithRetry access to the running spinner handle.
