Implement Compose graphics resolvers (Color, ColorStrategy, SolidColor) #81

Description

Add ColorResolver and SolidColorResolver for androidx.compose.ui.graphics.Color and androidx.compose.ui.graphics.SolidColor, plus ColorStrategy to control color generation mode. All live in dev.appoutlet.some.android.

• Scope and constraints

  • ColorStrategy is a sealed interface extending Strategy with variants: RandomArgb (default), RandomHsl, Palette (with a fixed color list). It lives in dev.appoutlet.some.android.strategy.
  • ColorResolver generates Color(red, green, blue, alpha) with randomized components when using RandomArgb; uses HSL conversion for RandomHsl; picks from the configured palette for Palette. Constructor receives strategyProvider: StrategyProvider and random: Random. It lives in dev.appoutlet.some.android.resolver.compose.
  • The resolver fetches the strategy once in init: strategyProvider.get<ColorStrategy>() ?: ColorStrategy.default.
  • SolidColorResolver creates SolidColor(color) by delegating to the chain to resolve a Color first. Constructor receives random: Random only. It lives in dev.appoutlet.some.android.resolver.compose.
  • Both canResolve() use exact type matching via typeOf<T>().
  • Each resolver has its own JVM unit test class. ColorResolver tests verify each strategy variant. SolidColorResolver tests verify it produces a SolidColor wrapping a non-null Color.
  • Depends on androidx.compose.ui:ui (transitively provides ui-graphics).

Scope

In scope: ColorStrategy sealed interface + variants, ColorResolver, SolidColorResolver, JVM unit tests.
Out of scope: registering resolvers in AndroidTypeResolverProvider (ticket #14).

Acceptance criteria

• ColorResolver generates colors in default RandomArgb mode
• ColorStrategy.RandomHsl produces valid HSL-converted colors
• ColorStrategy.Palette only produces colors from the configured list
• SolidColorResolver produces a SolidColor wrapping a non-null Color
• Each resolver's canResolve returns true for its own type and false for others
• Tests compile against android.jar with androidx.compose.ui:ui on classpath and run as JVM unit tests
