Ship a Q4_K_M GGUF so HF "Use this model" surfaces an Ollama snippet

Browse files

Until now this repo deliberately shipped no weights — users had to
clone, run make build, and let scripts/build.sh fetch a quant from
unsloth/Qwen3.6-27B-GGUF. That kept the repo small but meant HF's
"Use this model" widget could only show the Transformers snippet (HF
requires a GGUF in the repo to auto-generate the Ollama snippet).

Ship a single Janus-27B.Q4_K_M.gguf (~17 GB) so:
- `ollama run hf.co/FoolDev/janus-27b` works one-liner — Ollama
pulls this GGUF and applies the Modelfile in this repo (TEMPLATE,
PARAMETERs, SYSTEM all flow through, including the tool-calling
TEMPLATE we wired up in 80f4494).
- HF lists the repo under GGUF models (added `gguf` to tags).

Q4_K_M for parity with the 35B sibling and the README's default;
local builders who want Q3_K_S use `make build QUANT=Q3_K_S` as
before. Loosened .gitignore from `*.gguf` to `*.gguf` +
`!Janus-27B.*.gguf` so the upstream Qwen3.6-27B-*.gguf that
scripts/build.sh fetches is still ignored. README's "does not
redistribute weights" wording reworked — the wrapper philosophy still
holds for the upstream Qwen GGUFs, we just ship one tagged
distribution to back the HF/Ollama UX.
