Type safe experimentation
summary
Generates type-safe Kotlin accessors for Optimizely features and experiments to eliminate string-typo bugs and make unused flags discoverable, using Optimizely as source, KotlinPoet to emit sealed classes/objects and a generic variable type, and kotlin-compile-testing plus reflection to compile and assert generated code contains expected instance and key values. Adds a Gradle plugin and task that fetches flags, writes code into a package, and is verified with Gradle test runs; the demo generation and tests succeed.
