Antigravity usage now appears in the interactive dashboard, and table headers no longer stay as raw lowercase IDs
When checking usage with usage, if Antigravity was installed, switching to the interactive dashboard previously only showed a blank tab with No data.
The problem was that the dashboard and usage report each maintained separate agent-to-loader mapping tables. Previously, only the report included antigravity, so even though the report command could load usage, the dashboard tab for a detected installation still rendered No data. Terminal tables also lacked Antigravity's short and display names, leaving column headers stuck with the raw lowercase agent ID. The two mapping tables previously lacked consistency checks, and the initial regression tests (automated checks preventing existing features from breaking) even hard-coded three known agents instead of comparing both lists, failing to keep keys synchronized; tests now enforce exact key equality across both sides.
