Sends a string to the standard input of a background process. The target process must have been started with stdin: true in the run command request so that a stdin pipe was reserved. Returns an empty {} body.
For full interactive stdin with streaming output, back-pressure, and separate stdout/stderr callbacks, see the dedicated stdio API. This command-level endpoint is a simpler alternative for one-shot stdin writes.
