Added mcpName and repository fields to package.json
- PyPI servers (fetch, git, time):
Added mcp-name comment to README.md
Part of #3047
Update the SDK from ^1.19.1 to ^1.23.0 in all TypeScript reference servers:
- everything
- filesystem
- memory
- sequentialthinking
Also update everything server for SDK breaking changes:
- Update zod to ^3.25.0 (zod v4 compatibility)
- Fix ToolInput/ToolOutput types to use Tool["inputSchema"] instead of
inferring from zod schemas
- Fix result.content handling to support array format

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.
