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.

+# Serve inclusionAI Ling-3.0-flash (Q6_K) on dankclaw as a TRIAL, replacing
+# frank-default-large temporarily.
+#
+# Runtime: llama.cpp FORK (aetherbird bailingmoe3-support) - stock llama.cpp
+# cannot load the bailingmoe3 architecture. Backend: Vulkan (RADV) on the
+# Strix Halo APU; memory is the shared 128 GB pool (96 GiB UMA + GTT that
+# Vulkan exposes as an ~111 GiB heap). MTP drafter is bundled in the same
+# GGUF (block 42) - no separate --spec-draft-model needed.
+#
+# Tie-back: to restore the Qwen3.6-27B service, stop frank-large-ling and
+# start frank-default-large (its env/unit are committed and unchanged).
+#
+# Tunables come from frank-default-large.ling.env in this directory unless
+# FRANK_LING_ENV_FILE overrides that path.
