Union of both branches' entitlements (aps-environment + location.push
from this branch, App Attest CDhash opt-in from PR #41). Signing
settings resolved to Manual/Apple Distribution/AppStore profile -
this branch independently introduced the same Automatic/Apple
Development regression as PR #41 (see e93ccd2); one line
(PROVISIONING_PROFILE_SPECIFIER) merged silently to the broken value
without a marked conflict, caught by manual review and corrected
alongside the marked conflicts.
com.apple.developer.devicecheck.appattest-environment was hardcoded to
"development" for every build, including the App Store/TestFlight
distribution build. Apple's App Attest servers validate this claim
against how the app was actually signed/distributed, so a "development"
claim on a real distribution build fails - guest session handshake
never gets past the challenge step, no store/city data ever loads.
Parameterized per configuration: development for Debug, production for
Release, via an APP_ATTEST_ENVIRONMENT build setting.
Adds a pre-login public store locator (guest session via DeviceCheck/App
Attest, keychain-backed token storage) so the app no longer forces sign-in
before showing any content, plus updated support URL metadata.
