Detailed Description

UI-independent acquisition and measurement helpers for Audio Scope.

These helpers run on copied, non-realtime sample data. They never touch the audio callback, never allocate on the realtime path, and do not own any UI behavior. The live inspector, CLI, MCP, and future offline sources can all share this one trigger/measurement implementation.
