Subject: [PATCH 2/2] hotfix: use NUL-delimited IPC for dispatch command
 builder

build_dispatch_cmd() used echo (newline-delimited) to pass arguments
back to cmd_dispatch(), but multi-line prompts (worker restrictions,
memory context) caused read -r to split a single prompt argument into
multiple array elements. Workers received the prompt as many separate
positional args instead of one, causing opencode to misparse and exit
with help text.

Fix: use printf '%s\0' (NUL-delimited) output and read -r -d '' to
preserve multi-line strings as single arguments through the IPC
boundary.
