Add audience-specific Where builds

Summary

• add explicit Where Development, Where Beta, and Where App Store schemes over one target family
• keep audience compiler conditions on the app, widget, and share-extension hosts while injecting App Group, storage, widget, intent, and icon behavior into package modules
• isolate the Development bundle family and local-only store; retain the shared production identity and CloudKit store for Beta and App Store
• make primary app icons audience-configurable and prevent ./icons from deleting any asset currently configured as an audience primary

Design notes

Audience metadata remains centralized in Project.swift. The icon tool reads those descriptors when guarding removal, so it does not introduce a second primary-icon configuration. Enterprise distribution remains intentionally out of scope.

Validation

• mise exec -- tuist build "Where Development"
• mise exec -- tuist build "Where Beta"
• mise exec -- tuist build "Where App Store"
• ./test --all — 1,626 tests passed
• ./swiftformat --lint
• bash -n icons and bash -n Where/install
• fixture regression: a non-base audience primary is refused by ./icons --remove, with catalogs and manifest unchanged

Review focus: this intentionally reads the literal primaryAppIconName fields from Project.swift so audience primaries retain one source of truth. It fails closed if that descriptor shape stops yielding any names; the regression fixture also verifies a non-base configured primary cannot be removed.
