Drag & Drop Files

When the user drag-drops a PDF (or any supported file) into a chat-style MCP host such as Claude Desktop, Cowork, or Cursor, the file lands in a host-owned sandbox directory the MCP server cannot read. The path the host hands the agent is meaningless to a separately-running npx MCP process.

@talonic/mcp@0.1.4 and later solve this by accepting `file_data` (base64-encoded file bytes) and `filename` on talonic_extract and talonic_to_markdown. The agent reads the file bytes from the conversation, base64-encodes them, and passes them through the MCP tool call. The MCP server decodes, infers MIME type from the filename, and uploads to the Talonic API.
