docs: say where to get Blender in the quick start

The quick start hands the reader a `blender --background --python ...`
command without ever saying where `blender` comes from or which versions the
repository supports. The supported-versions table is further down the page
and links nowhere.

Add one bullet above the run command: the LTS download link, which of 5.2
and 4.5 is primary, and the macOS app-bundle path that trips people up when
`blender` is not on PATH.

 - **Cursor** — point Cursor at the checkout (or symlink `rules/` into your project). The `.mdc` rules apply automatically by glob scope; skills are referenced by name in chat.
 - **Claude Code** — copy `skills/` and `rules/` into your project workspace, or keep this repo as a checkout that Claude Code references directly.
+- **Get Blender** — download **5.2 LTS** (primary target) or **4.5 LTS** (supported fallback) from [blender.org/download/lts](https://www.blender.org/download/lts/); current stable lives at [blender.org/download](https://www.blender.org/download/). The `blender` command below is that binary — on macOS it is inside the app bundle at `/Applications/Blender.app/Contents/MacOS/Blender`.
 - **Run an example** — every example is a self-checking headless script (exit non-zero on failure, no GPU needed for the check):
