  // Notes:
  // - BUN_GARBAGE_COLLECTOR_LEVEL=2 forces GC to run after every `expect()`, but is slower
  // - BUN_DEBUG_QUIET_LOGS=1 disables the debug logs
  // - FORCE_COLOR=1 forces colors in the terminal
  // - "${workspaceFolder}/test" is the cwd for `bun test` so it matches CI, we should fix this later
  // - "cppvsdbg" is used instead of "lldb" on Windows, because "lldb" is too slow
  // - Seeing WebKit files requires `vendor/WebKit` to exist and have code from the right commit.
  //   Run `bun sync-webkit-source` to ensure that folder is at the right commit. If you haven't
  //   cloned it at all, that script will suggest how.
