v0.2.5

Added

• Custom (non-contract) fields on Create/Update and Invoke Action. A new
  Custom Fields collection (View / Field / Type / Value) assembles
  Acumatica's custom block in the request body, with the type token driving
  JSON coercion (boolean / integer / decimal / string). Read them back with the
  $custom query parameter.
• Usable as an AI tool. The nodes now expose a …Tool variant, so they can
  be connected to an MCP Server Trigger or an AI Agent and called as tools.
