Subject: Add IMGGEN_WIDTH/IMGGEN_HEIGHT default size to .env

Bare prompt runs used the downstream 1024x1024 default. Now the wrapper
seeds -W/-H from IMGGEN_WIDTH/IMGGEN_HEIGHT in .env when the flags are
absent; -W/-H still override. .env.example documents the vars, notes the
multiple-of-8 SDXL constraint, and suggests 1280x960 (landscape).
