ruview-harness-v0.3.1

`@ruvnet/ruview` 0.3.1 adds a safe discovery layer for contributors and local agents.

## Highlights

- New read-only `ruview_guidance` CLI/MCP tool.
- Topic filters for architecture, sensing, hardware, training, HomeCore, integrations, deployment, community, and testing.
- Every capability record includes maturity, evidence tier, repository citations, focused validation commands, and explicit limitations.
- Local checkout citations are existence-checked; catalog drift fails closed.
- Optional reviewed shared-brain matches are bounded and remain evidence, never authority.
- Honest HomeCore coverage for startup restore, native/Wasmtime plugins, HA-compatible REST/WebSocket, HAP pairing/mDNS, migration, and STT/TTS satellite contracts.
- New public `@ruvnet/ruview/guidance` ESM export and release-tarball smoke coverage.

## Install

```bash
npx @ruvnet/ruview@0.3.1 guidance --topic homecore --query "Wasmtime plugins"
npx @ruvnet/ruview@0.3.1 mcp start
```
