Pull request overview

Adds a new Metrics module to the Firebolt C++ client (public API, implementation, tests, demo app integration) and aligns shared AgePolicy typing across modules/specs.

Changes:

• Introduces Firebolt::Metrics API (IMetrics), implementation (MetricsImpl), and unit/component tests.
• Centralizes AgePolicy into a shared firebolt/common_types.h and updates Discovery + JSON enum mapping accordingly.
• Updates OpenRPC spec artifacts to include Metrics methods/schemas.
