Updated README - autodiscovery in copy ops

 Updated `build-and-copy.sh` to support copying to multiple hosts (thanks @eric-humane for the contribution).
 - Added `-c, --copy-to` (accepts space- or comma-separated host lists) and kept `--copy-to-host` as a backward-compatible alias.
 - Added `--copy-parallel` to copy to all hosts concurrently.
+- Added autodiscovery support: if no hosts are provided to `--copy-to`, the script detects other cluster nodes automatically.
 - **BREAKING CHANGE**: Short `-h` argument is now used for help. Use `-c` for copy.

+**Build and copy using autodiscovery:**

+If you omit the host list after `--copy-to`, the script will attempt to auto-discover other nodes in the cluster (excluding the current node) and copy the image to them.
