gad:auto-conventions

Check if CONVENTIONS.md already exists:

test -f .planning/CONVENTIONS.md && echo "EXISTS" || echo "MISSING"

If EXISTS, update it with new patterns. If MISSING, create it.

Scan the codebase for established patterns:

• File naming (kebab-case, PascalCase, etc.)
• Directory structure
• Import/export patterns
• State management patterns (zustand, redux, etc.)
• Component patterns (functional, class, etc.)
• Type conventions (interfaces vs types, naming)
• Test patterns

Write .planning/CONVENTIONS.md with the discovered patterns.

Commit:

git add .planning/CONVENTIONS.md
git commit -m "docs: auto-scaffold CONVENTIONS.md from codebase patterns"
