- dish_added now carries a `source` param; onboarding-created dishes fire
it with source="onboarding" (previously untracked, undercounting activation)
- onboarding_completed now reports dish_count
- premium_purchased tagged with StoreKit environment (production/sandbox/xcode)
so test purchases can be excluded from conversion metrics
- add .gitignore to keep signing secrets (.p12/.cer/.mobileprovision) and
build artifacts out of the repo
- document branch↔MARKETING_VERSION naming convention
