Pull request overview

This PR adds support for a new "analysis" measurement mode to the CodSpeed benchmarking framework. The analysis mode enables instrumentation similar to simulation mode and integrates with instrument hooks for tracking benchmark execution.

Key changes:

• Introduced a new Analysis variant to the MeasurementMode enum
• Integrated InstrumentHooks for tracking benchmark lifecycle events
• Removed the deprecated is_instrumented() function and RunningOnValgrind enum variant

Reviewed changes

Copilot reviewed 9 out of 9 changed files in this pull request and generated 4 comments.

olgtm, although CI outputed the No performance analysis stuff, is this expected with memory mapping not being merged all the way ?
