Implement Pair, UserHandle, and Color resolvers #79

Description

Add resolvers for android.util.Pair, android.os.UserHandle, and android.graphics.Color. Each resolver lives in dev.appoutlet.some.android.resolver.

• Scope and constraints

  • PairResolver — Pair(first, second) where first and second are resolved by delegating to the chain for generic type arguments. Constructor receives random: Random only; type args are extracted from KType.arguments in resolve().
  • UserHandleResolver — guarded by Build.VERSION.SDK_INT >= 24; generates via UserHandle.of(uid) with random non-system UID (≥ 10000). Falls back to null on API < 24. Constructor receives random: Random only.
  • ColorResolver (for android.graphics.Color) — guarded by Build.VERSION.SDK_INT >= 26; generates via Color.valueOf(red, green, blue) with randomized RGB values. Falls back to null on API < 26. Constructor receives random: Random only.
  • Each canResolve() uses exact type matching via typeOf<T>().
  • Each resolver has its own JVM unit test class. UserHandle and Color tests verify type matching and API-level guard logic. Pair tests verify both generic args are resolved via chain delegation.
  • Follows the same patterns as simple resolvers from :core.

  • Prerequisite: Set up :android module with Android Library plugin and dependencies #75 (:android module setup)

Scope

In scope: 3 resolver classes + 3 test classes.
Out of scope: Account and Location (handled by existing ClassResolver), registering resolvers in AndroidTypeResolverProvider (ticket #14).

Acceptance criteria

• PairResolver generates pairs where first and second are resolved via chain delegation for generic type args
• UserHandleResolver generates a UserHandle when Build.VERSION.SDK_INT >= 24, returns null otherwise
• ColorResolver generates an android.graphics.Color when Build.VERSION.SDK_INT >= 26, returns null otherwise
• Each resolver's canResolve returns true for its own type and false for other types
• All tests compile against android.jar and run as plain JVM unit tests
