Local LLM guidance

AMD specifies 16 GiB of GDDR6 memory for the RDNA 2 Radeon RX 6800 XT; no runtime or performance behavior is inferred.

LLMGauge uses dedicated VRAM as the conservative GPU-capacity signal. Integrated/shared-memory graphics are not treated as dedicated GPU capacity by the current engine, so those systems may be classified as CPU-only even when the operating system can share RAM with graphics.
