agvtool doesn't apply here — no VERSIONING_SYSTEM set, CURRENT_PROJECT_VERSION
comes from Skip.env (shared with the Android side) via #include in
Darwin/PediFoods.xcconfig. Bump it there instead.
Dropped APPLE_ID, ITC_TEAM_ID and unused BITRISE_DISTRIBUTION_METHOD carried
over from LC Wallet's Fastfile/Appfile shape — none of them are read anywhere
in this project's Appfile or Fastfile.
Added the actual missing piece: DEVELOPMENT_TEAM, which both
Darwin/PediFoods.xcconfig and Darwin/fastlane/AppStore.xcconfig leave blank
on purpose for CI to fill in. Wired BITRISE_DISTRIBUTION_METHOD into
build_app's export_method so it stops being dead config.
Modeled on LC Wallet's bitrise.yml. Push-only trigger map (develop->beta,
main->release), no PR-triggered checks. Reuses the existing Skip fastlane
lanes directly instead of a generic xcode-archive step, since build_app
already carries the Skip-specific xcconfig and build flags. Adds a beta
lane (TestFlight) to match release, which was the only lane wired before.
