APEX 4.2 — Zero-friction setup, auto-generated CLAUDE.md

What's new in 4.2

New: /setup command
Run this once on any project: new or existing. Auto-detects your stack,
generates CLAUDE.md automatically, seeds the project brain, warms the plan
cache. Full onboarding in under 2 minutes with no manual config.

New: generate_claude_md.py
Auto-generates a correct, production-ready CLAUDE.md from your actual project.
Reads package.json / requirements.txt / go.mod, detects framework version,
generates matching Hard Rules, conventions, and Good Pattern for your stack.

Fix: Python 3.8 and 3.9 compatibility
All 11 intelligence modules now work on Python 3.8+. Previously would crash
on import with a TypeError on older Python versions.

Fix: Windows atomic writes
All file write operations now use os.replace() throughout. No data loss on
interrupt, no FileExistsError on Windows Git Bash second run.

Upgrade from 4.1

bash install.sh --update

Preserves your CLAUDE.md, brain, trajectories, and taste memory.
Updates commands and intelligence modules only.
