0.15.3: Android 16 compatibility hotfix

[llblab]

Summary

This hotfix updates Android release builds to compile against and target Android 16 (API level 36), satisfying the Google Play target API requirement without raising Bubblewrap's minimum supported device SDK.

It also refreshes the compatible Svelte, Vite, Stylelint, Prettier, libp2p, and utility dependency set.

Why

Google Play requires a newer target API for release acceptance. Bubblewrap hardcodes this value in generated Gradle output rather than exposing it through the TWA manifest.

User-visible behavior

• Android packages target API 36 while retaining existing minimum-device compatibility.
• Release generation fails clearly if Bubblewrap changes the expected Gradle template shape.
• Application and Android package versions advance to 0.15.3 / versionCode 15003.

Changed areas

• Android CI: Applies and verifies compile/target SDK values after Bubblewrap project generation.
• Dependencies: Updates all direct npm dependencies to their latest compatible releases.
• Documentation and release metadata: Records the target-SDK contract and 0.15.3 hotfix.

Risk Notes

• The change affects generated Android Gradle configuration only; web gameplay and deterministic replay logic remain unchanged.
• The SDK patch has focused tests and fails closed on template drift.
