Vector Setup

Bootstraps ruvector@0.2.25 and its optional add-ons so every /vector subcommand actually works on first run.

Why this exists

Out of the box, several /vector subcommands fail with a confusing dep error:

Error	Missing package
`ONNX WASM files not bundled. The onnx/ directory is missing.`	`ruvector-onnx-embeddings-wasm`
`Brain commands require @ruvector/pi-brain`	`@ruvector/pi-brain`
`SONA not available. Native error: Cannot find module '/.../@ruvector/sona/index.js'`	`@ruvector/ruvllm` (JS fallback)
`LLM commands require @ruvector/ruvllm`	`@ruvector/ruvllm`

This skill installs them in one pass.
