v1.3.1

Docs-only patch. v1.3.0 published kairo-mcp to npm; v1.3.1 reflects
that in the README badge row so visitors see the published version
and download count at a glance.

Added

• README badge row gains two real, dynamic shields:
  • [![npm](.../npm/v/kairo-mcp)](npmjs.com/package/kairo-mcp) —
    latest published version, pulled live from the npm registry.
  • [![npm downloads](.../npm/dm/kairo-mcp)] — monthly download
    count.
    Both are dynamic; both will tick upward (or sideways) on their own
    as downstream users npm install the package.

Notes

• No code changes. No schema changes. No MCP contract changes. No
  CLI behaviour changes. No stability registry changes. Pure docs.
• Tag v1.3.1 is shipped to GitHub for completeness, but a re-
  publish to npm is NOT required — npm's badge endpoint serves the
  latest version regardless of repo tags, and the published tarball
  for kairo-mcp@1.3.0 is unchanged.
• A separate npm publish for 1.3.1 is optional. If desired, run
  npm publish per PUBLISHING.md — but the README badges work
  whether or not you do.
