📜 Description

Collection branch for the Micrometer metrics integration stack.

The stack adds a framework-neutral sentry-micrometer registry, active and passive meter mappings, separately reviewed FunctionTimer semantics, and opt-in Spring Boot 2, 3, and 4 auto-configuration.

💡 Motivation and Context

Micrometer users currently need custom code to send application metrics to Sentry. This stack makes Sentry an additional Micrometer destination while preserving existing registries and reusing the SDK's metrics pipeline.

💚 How did you test it?

Each stack PR includes focused tests for the capability it introduces. The final PR adds cross-registry and Spring Boot validation.
