Report on teammate @mentions (who tags who)

I’d like the ability to report on how often teammates @mention each other in conversations, including who tagged whom and how frequently over time.

This would help us:

• Measure how much support teammates need during onboarding and training
• Identify patterns where certain teammates rely heavily on others
• Track improvement over time as teammates become more independent

Ideally, this could be visualized in reports (e.g. charts) and filtered by teammate, time period, and team.
