chore: install blender-skills 1.3.0 for modelling work

94 MIT-licensed skill packs plus their shared references, copied unedited from
the local checkout of github.com/arjun988/blender-skills at commit 8f778d2
(1.2 MB, 269 Markdown files). They are agent instructions, not add-ons; the
pipeline still drives Blender headlessly through bpy, so the optional Blender MCP
server is not required. Provenance recorded in THIRD_PARTY_NOTICES.md and the
version, source, and update procedure in Docs/toolchain.md.

+`.agents/skills/blender-skills/` holds 94 Blender skill packs (MIT, v1.3.0) — `blender-modeler`, `hard-surface`, `uv-workflow`, `collision-proxy`, `archviz`, and so on. They are instructions for the agent, not add-ons, and nothing in the pipeline depends on them. Provenance in `THIRD_PARTY_NOTICES.md`.

 ## Blockout

 Unreal Engine 5.9 is in preview and Unreal Engine 6 has been announced as of November 2026. Neither is a pin candidate for `0.x`. One engine family per milestone; a family change is a breaking change and belongs in `CHANGELOG.md`.

+These are instructions and reference notes for agents, not code that runs in a build. Four of them assume a **Blender MCP server**; this project drives Blender headlessly through `bpy` (`Tools/*.py`) instead, so MCP is optional and nothing depends on it.
+
+To update: copy `.claude/skills/` from a newer upstream checkout over the existing directory, then record the new version and commit hash in this table. Skills are read on demand, so the harness catalog may need a reload before they appear as first-class entries.

 ## Pin rules
 
 - One engine build per release. Record the launcher or source build, the patch version, and the build date in this file and in the release entry.
