Document current coding-workflow stack state

Snapshot of where opencode + Qwen3-Coder + MCPs + Kimi-Linear + voice
  + Phoenix tracing land today, plus in-flight (oc-tree, kimi-linear
  context ramp) and next (ComfyUI) items with pointers to per-project
  NEXT_STEPS.md guides.

+# Derived image: kyuz0:stable plus gfx1151 AITER GEMM config fallbacks.
+#
+# kyuz0's image is built for gfx1151 but doesn't ship every per-op AITER
+# autotuning config. Kimi-Linear's MLA layers hit FP8 BMM ops
+# (BATCHED_GEMM-A8W8-A_PER_TOKEN_GROUP_PREQUANT_W_PER_BATCHED_TENSOR_QUANT
+# and friends) that have no gfx1151 config in the bundle. We synthesize
+# them by copying from the closest-arch config that does exist (RDNA3
+# gfx1100 is closest to RDNA3.5 gfx1151). Tile sizes won't be optimal
+# but the kernels will compile and run.
+#
+# Idempotent — only fills slots that don't already have a gfx1151 config.
+#
+# If we ever need a vLLM-pinned base (e.g. upstream regresses on
+# Kimi-Linear), build it via ./build.sh first and change FROM here to
+# kimi-linear-local:v0.11.2.
