docs: use @beta install tag and add NitroX tools to README

- Change install command to sf plugins install @provartesting/provardx-cli@beta
  across README.md and docs/mcp-pilot-guide.md
- Add 5 NitroX (Hybrid Model) tools to the TOOLS EXPOSED list in README:
  provar.nitrox.discover, read, validate, generate, patch
  (present since beta.2, missing from docs)

Note: provar-mcp-public-docs.md and university-of-provar-mcp-course.md
are maintained separately — flag for manual update of install tag.
