Parse from $ARGUMENTS:

• --path <local-path> — analyze a local directory
• --repo <github-url> — clone from GitHub and analyze
• --branch <branch> — branch to clone (default: default branch)

1. Acquire the target:

   • If --repo: clone to temp with git clone --depth 1 <url> /tmp/gad-re-<name>
   • If --path: use the local path directly
   • If the URL includes /tree/<branch>/<path>, extract the subdirectory

2. Run the deep analysis — follow the 5-pass methodology in the skill.

3. Produce all outputs — REQUIREMENTS.xml, DECISIONS.xml, CONVENTIONS.md, ROADMAP.xml, CONTEXT.md

4. Clean up — if cloned to temp, remove the temp directory
