feat: add MCP SDK 1.24+ compatibility (#19)

Support both  (SDK 1.23-) and  (SDK 1.24+) property
  names in RegisteredTool to maintain backwards compatibility.

  Changes:
  - Update RegisteredTool type to accept either callback or handler
  - Add utility functions to abstract property name detection
  - Extract MCP SDK compat helpers into dedicated module
  - Preserve original property name when wrapping tools
  - Remove 1.24 version restriction from CI compatibility workflow

  Tested with MCP SDK versions 1.23.0 and 1.24.2.
