fix: bump MCP SDK to >=1.23.0 for protocol 2025-11-25 support (#118)

Claude Desktop now requires MCP protocol version 2025-11-25, but
mcp v1.16.0 only supports 2025-06-18. This causes Claude Desktop
to silently refuse to expose tools despite a successful handshake.

Bumps mcp[cli] from >=1.3.0 to >=1.23.0,<2 (resolves to v1.26.0).
The <2 upper bound avoids upcoming v2 breaking changes per upstream
SDK guidance.
