v0.3.2 - multi-line interactive paste fix

Fix

Interactive mode no longer breaks when you paste a multi-paragraph image prompt.

• Multi-line prompts: paste freely, end with a line containing only --- (or Ctrl-D)
• Shared stdin reader: later wizard questions no longer steal paste lines
• Command recovery: if you paste the prompt on the Command step, it is treated as generate
