Issue Discovery by Prompt (Codex Version)

Goal

Prompt-driven issue discovery with intelligent planning. Instead of fixed perspectives, this command:

1. Analyzes user intent to understand what to find
2. Plans exploration strategy dynamically based on codebase structure
3. Executes iterative exploration with feedback loops
4. Performs cross-module comparison when detecting comparison intent

Core Difference from issue-discover.md:

• issue-discover: Pre-defined perspectives (bug, security, etc.), parallel execution
• issue-discover-by-prompt: User-driven prompt, planned strategy, iterative exploration
