Subagent explore report

When to use

• Parent session delegates "Explore premflow / elomaxz at {REPO_ROOT}"
• Subagent turn pattern: UpdateCurrentStep → Glob → Grep → Read (corpus subagent turns)
• Need structure, CMake/Makefile, MVU entry points before parent implements

Steps

1. Glob key paths (CMakeLists.txt, main.c, include/, src/).
2. Grep MVU/model symbols (model_, Program, elomaxz).
3. Read README, build files, and primary entry (main.c / app.c).
4. Return concise report sections:
   • Directory layout
   • Build system (CMake vs Makefile)
   • MVU/state entry points
   • Dependencies (e.g. elomaxz FetchContent)
   • Risks or gaps for the parent's plan
