CCR worker requests can now target a custom session URL instead of the default endpoint

What

The function that sends CCR worker requests to a Claude session now checks for a ccrSessionUrl() value from the host's launch options first. If one is set (with any trailing slashes removed), it's used as the base address for the /worker/... call; otherwise Claude Code falls back to the default .../v1/code/sessions/{id} URL. When a socket is used for the connection, the log now also notes "over ${socket path}" for extra context.

Why

This allows worker requests to be redirected to a non-default session endpoint, useful when a session isn't reachable at the standard URL.
