Pull request overview

This PR adds telemetry logging for the adaptive aggressiveness feature used in the Xtab inline edits system. The changes enable data collection to analyze and validate the user happiness score algorithm by recording the aggressiveness level and happiness score when inline edits are shown.

Changes:

• Modified getAggressivenessLevel() to return both the aggressiveness level and the user happiness score as an object to avoid race conditions in telemetry logging
• Added telemetry builder methods (setXtabAggressivenessLevel and setXtabUserHappinessScore) to capture these values
• Updated telemetry metadata with proper GDPR annotations for the new fields
• Logged telemetry only when using the XtabAggressiveness prompting strategy
