Code Lens for Git "Team Activity View"

Introduced the 'Team Activity View' popup for CodeLens in Dev14, replacing the previous popup triggered from the authors indicator. This new view presents commit information graphically, detailing how many changes were done by how many authors over a period of time. Each commit is represented by a shape (dot or triangle) with color mapping to authors, and the horizontal axis shows days since the commit. Hovering reveals commit details, and right-clicking offers contextual actions like viewing commit details or contacting the author. Different shapes denote edits or merges. A legend maps colors to authors, grouping older authors under gray. The view is dockable and adjusts to available horizontal space. This view helps answer questions about code churn and identify knowledgeable individuals for specific code sections.
