Drop any file to hand its path to the agent

Dropping a screenshot on the microphone or a text field has always attached it. A PDF, log or spreadsheet dropped there used to open in a new browser tab, and the agent never got it. Now the file's own path goes into the field at the cursor, the way a terminal agent gets a file dragged into it, so the agent can read the file and also move or change it where it lies. In a browser, Obeya finds the file on its machine by name, size and time; the Obeya app takes the path from the system. With no card open, the file waits beside the microphone and goes with the next voice message.
