feat(harness): npx @ruvnet/ruview operator harness + ADR-182 (#1123)

A host-portable RuView agent harness minted via MetaHarness and hardened
per ADR-182. Published as @ruvnet/ruview@0.1.0 (bare `ruview` blocked by
npm's typosquat filter → scoped fallback).

What it does:
- 6 fail-closed `ruview.*` tools (onboard, claim_check, verify,
  node_monitor, calibrate, node_flash) exposed as CLI verbs + a
  dependency-free MCP stdio server.
- The "prove everything" rule made executable: `ruview.claim_check`
  flags untagged accuracy claims and the retracted "100%" framing.
- 5 host-neutral skills (onboard/provision-node/calibrate-room/
  train-pose/verify) + bundled .claude/ config + provenance manifest.

Validated: 17/17 unit tests, live MCP handshake, `ruview.verify` ran the
real verify.py to VERDICT: PASS, clean `npx @ruvnet/ruview` from registry.
Packs to 16.7 kB / 21 files; kernel+host are optionalDependencies so the
operator tools install lightweight.

README: documented as the portable, multi-host companion to the in-repo
plugins/ruview/ Claude Code plugin (not a replacement).
