This commit ports the comprehensive elicitation field type demonstration
from modelcontextprotocol/example-remote-server PR #17 to the everything
server, while maintaining the better UX of the existing implementation.

Changes:
- Expanded elicitation schema to demonstrate 9 field types:
  * string (plain and with default values)
  * boolean
  * email (format: "email")
  * uri (format: "uri")
  * date (format: "date")
  * integer (with min/max and default)
  * number (with min/max and default)
  * enum with enumNames for human-readable labels
- Added required fields support (name field is required)
- Added 10-minute timeout to elicitation request
- Improved response handling to dynamically show all provided fields
- Updated tool description to reflect comprehensive field type support
- Removed unused requestElicitation helper function (inlined implementation)
- Removed unused ElicitRequest import

The implementation follows PR #17's approach of directly using
extra.sendRequest() while preserving the user-friendly response handling
with emojis and formatted output from the original implementation.
