Suppress startElicitation tool if client does not advertise support for elicitation capability

Browse Source 
* In everything.ts
  - remove inappropriate elicitation entry from server capabilities (this is a client capability)
  - When creating tool list, only add `ToolName.ELICITATION` definition to tools array if `clientCapabilities` includes `elicitation`

* In package.json / package-lock.json
  - bump @modelcontextprotocol/sdk to "^1.17.4", adding `elicitation` to `ClientCapabilities` type
