Fix multi-block resize bug: extension placement now resizes controller

Bug: When block B was placed next to already-running block A, the rescanGroup() on B detected A as controller but never told A to resize its terminal to the combined dimensions. A kept running at 80x24 instead of resizing to the group size. Fix: The propagation loop now checks if a member is the controller with a running terminal and resizes it to match the new group. Added test: extensionResizesRunningController verifies that placing an extension next to a running controller updates its cols/rows. 35 GameTests + 52 Rust tests, all passing.
