Add Play and FOSS distributions

[75py]

Summary

• add play and foss distribution flavors on the shared Android 16 / targetSdk 36 codebase
• keep the existing Play application ID with AdMob 25.4.0 and the official UMP consent/privacy-options flow
• add a co-installable FOSS application ID with no Ads/UMP/Google OSS runtime, network permissions, ad metadata, or automatic communication
• replace Google OSS Licenses with an offline Licensee-generated dependency catalog shared by both variants
• make Play release ad configuration fail closed, while CI test-ad bundles use the non-publishable .ci application ID
• build, lint, test, and report informational Kover coverage for both variants in CI

Validation

• ktlintCheck
• testPlayDebugUnitTest testFossDebugUnitTest
• koverXmlReportPlayDebug koverXmlReportFossDebug
• lintPlayRelease lintFossRelease
• assemblePlayDebugAndroidTest assembleFossDebugAndroidTest
• bundlePlayRelease -PallowTestAds=true (com.nagopy.android.aplin.ci)
• missing Play ad properties and test IDs without explicit CI opt-in both fail validation
• assembleFossRelease succeeds without ads.properties
• FOSS release dependency, manifest, resource, asset, and DEX audits found no Ads, UMP, Google OSS, network permission, AD_ID, ad metadata, or ad IDs
• API 37 emulator: Play/FOSS debug variants installed side-by-side and launched; list, settings, FOSS license catalog, and distribution-specific controls were checked

Known validation boundary

The Play connected suite reached 8/9 completed with 0 failures, then the existing LoadPackagesUseCaseTest stalled while navigating Android Settings. It was stopped, so the FOSS connected suite was not run. Both instrumentation APKs compile successfully.

Managed-emulator CI, clean-tag reproducibility proof, complete third-party NOTICE/copyright text packaging, release signing, F-Droid metadata, and store-console changes remain separate release work.
