v1.1.0 Update

Added editor and engine features for VSCode workspace support, WAV audio import but currently no playback, and richer OBJ/model metadata. 

Added a new `p64 vscode` CLI command and generates `.vscode/` files and packages/P64Generated helpers so projects can get automatic Pylance/launch/task/configuration support. 

Introduced automatic WAV import (mono, 16-bit, capped sample rate) with AudioClip sidecars and an AudioSource component + inspector UI and play controls. OBJ import now supports a 'model' mode with per-mesh entries, bounds, triangle/vertex stats, and wireframe data reused by previews and gizmos; the inspector displays model mesh summaries and a wireframe preview. 

Updated docs and sample project to demonstrate these changes and migrated scripting examples to use GameScript where appropriate.
