Use when the user asks to send multiple photos/files to a Zalo contact or group at once, or when openclaw's built-in single-media send is not enough. Supports local file paths and URLs. Requires Zalo credentials already set up via openclaw zalouser channel.

- Credentials are read from
~/.openclaw/credentials/zalouser/credentials.json(managed by openclaw, no re-auth needed) - ZCA_PATH is hardcoded to the openclaw-bundled zca-js. If openclaw is updated/reinstalled, the path may need updating in
scripts/send.mjs - Local files must be readable by the current user
- Zalo may have undocumented limits on number of attachments per message (tested up to ~10 without issues)
- Exit 0 = success, exit 1 = error
