ci: auto-publish mcp-server to npm via OIDC trusted publishing

Publishes @next-ai-drawio/mcp-server when packages/mcp-server changes on
main and the package.json version isn't on npm yet. Uses npm trusted
publishing (OIDC) - no token secret, no OTP, works with the strictest
2FA setting.

- * XML the model last saw (get_diagram) or wrote itself (create_new_diagram /

- *
- * "Matches" is structural, not byte-for-byte: draw.io re-serialises the
- * document when it pushes state back (different attribute order, pretty-
- * printed whitespace, regenerated diagram ids, viewport attributes like
- * dx/dy/pageWidth on <mxGraphModel>, a different mxfile host). None of that
- * is a user edit, so the fingerprint keeps only what a user can actually

 - Use add_page to append a new page (without losing existing ones — unlike create_new_diagram which REPLACES everything)
 - Use rename_page / delete_page for management
