Pull request overview

Migrates the Android release build configuration from the legacy minifyEnabled/shrinkResources/proguardFiles setup to the newer optimization { enable = true } DSL, and relocates the R8/ProGuard rules into the src/main/keepRules source set.

Changes:

• Switched the release build type to use optimization { enable = true } instead of the legacy shrinking configuration.
• Added androidApp/src/main/keepRules/proguard-rules.keep containing the project’s R8/ProGuard configuration previously embedded in the old pipeline.
