📌 Why this matters
Extension conflicts are notoriously difficult to diagnose because they often involve subtle interactions between multiple extensions rather than obvious failures. You might spend hours disabling extensions one by one, but this systematic approach cuts through that tedium by automatically testing different combinations. What makes this especially valuable is that many performance issues and mysterious bugs stem from extension conflicts that aren't immediately apparent - problems that seem like VS Code issues are often just two extensions stepping on each other's functionality in unexpected ways.
