refactor(action): simplify create issue and comment process

[github-actions]

Closes #261

Applied changes based on Issue #261.

I’ve updated the progress‐step definitions so that when you invoke the action with --create-issues, only the two steps “🔍 Gathering context” and “📝 Planning” are shown. For all other runs you still get the full four‐step flow:

• “🔍 Gathering context”
• “📝 Planning”
• “✨ Applying edits”
• “🧪 Testing”

Let me know if you’d also like to tweak any of the prompt wording or other behavior under the --create-issues flag!
