dankclaw: Ling-3.0-flash Q6_K trial config (Vulkan+GTT+draft-mtp)

Trial replaces frank-default-large temporarily via frank-large-ling.service
(port 7770, same alias). Requires the aetherbird bailingmoe3-support llama.cpp
fork at /home/dank/llama.cpp-ling (stock llama.cpp cannot load bailingmoe3).
Memory: 8x16GB LPDDR5 = 128GB physical; Vulkan exposes ~111.2GiB heap (UMA
96GiB + GTT) vs ROCm's 96GiB. Q6_K = 98.26GiB; MLA/KDA KV is tiny so 256k
ctx x 2 slots fits with ~10GiB headroom. Verified: loads ~45s, concurrent
streams both complete (no DFlash-style kill), ~7.7 t/s gen.
Restore Qwen: systemctl stop frank-large-ling; systemctl start
frank-default-large.

+# Memory model (amdgpu Strix Halo gfx1151, 8x16GB LPDDR5 = 128 GiB physical):
+#   - firmware UMA carve-out gives the iGPU ~96 GiB VRAM (rocm-smi "VRAM total").
+#   - CPU system RAM is the remainder (~30 GiB; kernel MemTotal).
+#   - Vulkan (RADV) reports an ~111.2 GiB heap (113910 MiB) - larger than ROCm's
+#     96 GiB, because Vulkan can also reach system memory via GTT.
+#   - Q6_K is 98.26 GiB, leaving only ~13 GiB of heap for KV + graphs, so keep
+#     the context small (Ling uses MLA/KDA, so KV stays small). Tune CTX_SIZE.
