Pull request overview

Updates the image generation demo documentation to focus on GPU/NPU deployment paths and expands guidance around SDXL and LoRA usage, while also adding CLI parameter documentation for LoRA registration.

Changes:

• Documented the --source_loras CLI parameter in the global parameters reference.
• Reworked the image generation demo to use GPU-oriented Docker/bare-metal commands, plus SDXL deployment and a “serve pre-downloaded model” option.
• Expanded the Multi-LoRA demo section with updated commands and embedded example outputs.

• For HF repo sources with an explicit filename (org/repo@file.safetensors), the filename should be the literal repo filename (spaces are allowed inside the quoted argument). Using %20 here will be treated as part of the filename and likely fail to resolve the file on HuggingFace.

• Same as the Linux example: for HF repo sources with an explicit filename (org/repo@file.safetensors), %20 will be treated as a literal part of the filename. Keep the real filename (with space) inside the quoted string.
