v2.1.4 - 360 VR panorama, Klein fine-tune, and INT8 acceleration

Added

• 360 / VR equirectangular panorama - Flux.2 Klein AND LTX-2.3 (two separate routes). The shared
  nomadoor/ComfyUI-Panorama-Stickers pack (MIT, Comfy Registry v1.3.0; four ERP nodes: Panorama Stickers /
  Cutout / Preview / Seam Prep) is documented model-agnostically in NODE_LIBRARY/custom-author.md - it is a
  360 projection tool, not a model-specific pack - and referenced from BOTH recipes. (1) Flux.2 Klein 360
  IMAGE (under FLUX.2 in MODELS.md): nomadoor's 360-ERP-outpaint LoRAs (flux-2-klein-4B-... apache-2.0,
  ...-9B-... license:other). (2) LTX-2.3 360 VIDEO (under LTX-2.3): text-to-360 via the public CivitAI LoRA
  360-degree panoramic shot - LTX-2.3 by Ragamuffin20 / Aitrepreneur (civitai.com/models/2327337, direct
  download api/download/models/2816797?fileId=2702793) - the LoRA the Floyo template wraps, which CORRECTS the
  prior "source unconfirmed" note - and flat-to-360 outpaint via TheBurgstall/VR-360-Outpaint-LTX2.3-IC-LoRA
  (cc-by-nc-4.0, v0.1 POC). Full card detail folded in from the CivitAI page: License LTXV2 (not the blanket
  "commercial-OK" I first wrote), trigger A 360-degree panoramic video, weight 0.6-1, aspect 2:1, the wrap-seam
  artifact the author reports fixed (civitai article 25291), plus true-VR finishing steps (mono->stereo via
  SamSeenX/ComfyUI_SSStereoscope, VR metadata via Google spatial-media). The Flux (image) and LTX (video)
  routes are unrelated and kept in their own model sections; neither cross-references the other for the pack.
• Flux2-Klein-9B-True-V3 (community fine-tune) recipe. A wikeeyang aesthetics / composition fine-tune of
  FLUX.2 [Klein] 9B (text-to-image + prompt-only instruct edit + LoRA face-swap / try-on + Mask+LoRA regional
  edit), with its full quant ladder (bf16 / fp8mixed / int8mixedrow / INT8-ConvRot / mxfp8 / nvfp4 /
  GGUF Q4_K..Q8_0). Added under FLUX.2 in MODELS.md, with a license caveat: the card is tagged Apache-2.0 but
  the weights derive from FLUX.2 [Klein], so verify the base license before commercial use. Distinct from
  nomadoor's 360-outpaint Klein LoRA above.
• INT8 inference acceleration note (ADVANCED.md). INT8 weight quantization is now native in ComfyUI
  (~1.5-2x over fp8 on 40-series+ per the source pack), which largely supersedes the ComfyUI-INT8-Fast pack;
  documented when to use the native loader vs the pack, the loader/naming mismatch, and convert_to_comfy.py
  for old quants, using the Flux2-Klein-V3 dual INT8 quants as the worked example.
• OCIO node docs refreshed to ComfyUI-OCIO v1.0.1 (NODE_LIBRARY/ocio.md, + a note in ADVANCED.md).
  Documented the v1.0.1 OCIO Write additions - colorspace_in_name (colorspace before the frame number,
  name_acescg.0086.exr), auto_colorspace (auto Rec.709 -> ACEScg when wired from LTX's HDR decode), and
  Nuke-style EXR compression - plus the new logc3 (ARRI LogC3) curve on OCIOLogConvert and a worked LTX-2
  HDR -> ACEScg EXR-sequence recipe (automatic + manual). Confirmed from the shipped v1.0.1 source; flagged that
  the pack's pyproject.toml still reads 1.0.0 at the v1.0.1 tag (a version-bump miss in the pack, not the docs).

Recipe / model counts are unchanged (still 68 recipes / 149 models). These are community fine-tunes / LoRAs / a
tool built on base models the count already includes (FLUX.2 Klein, LTX-2.3), so they add NO new official model -
the same double-counting reason the (fully PUBLIC) kijai ecosystem is documented in KIJAI.md rather than folded
into the 149. That is a SEPARATE exclusion from private / client-trained models, which is about IP, not
public-vs-not: kijai is fully public. The cover banner does not change.
