Relevancekit

This helps Claude write watchOS 26 widgets that use RelevanceKit to surface the right content at the right time in the Smart Stack. It covers two patterns: adding relevance() to existing timeline providers for supplementary hints, or building relevance-only widgets that appear solely when conditions match. The skill walks through time-based, location-based, fitness, sleep, and hardware relevance providers, plus how to combine multiple signals. Useful if you're building Apple Watch complications that need contextual intelligence, like showing a meeting widget only near the office or a workout widget when activity rings are incomplete. The API is watchOS-only despite being declared cross-platform, so iOS calls are no-ops.
