Add elicitation support to server-everything

[cliffhall]

In everything.ts

• import ElicitRequest and ElicitResultSchema from SDK
• refactor/rename GetTinyImageSchema to NoArgSchema, which will also be used for elicitation
• add ELICITATION to ToolName enum
• add elicitUserInput function that sends an ElicitRequest and returns the result
• in ListToolsRequest handler
  • add ToolName.ELICITATION entry
• In CallToolRequest handler
  • add ToolName.ELICITATION handler which calls elicitUserInput returns the formatted result message
  • In GET_TINY_IMAGE handler, remove GetTinyImageSchema.parse(args) since it has no args (like elicitation tool, and doesn't need to be parsed)

• In package.json

  • bump modelcontextprotocol/sdk to ^1.14.0

• Updated package-lock.json

Woops. I didn't notice that one, it was buried in a sea README updates. Shall I close this one then?

@cliffhall yes I think so, unless we have any strong feelings about one demo example being better than the other. :) I also added you as a reviewer there to get more 👀 before merging.
