install.sh: install the Rust maintenance worker (#10882)
* install.sh: install the Rust maintenance worker The release publishes weed-worker but the installer only knew weed and the Rust volume server, so the one binary that cannot be built without a Rust toolchain was the one you had to download by hand. --component all skips it on a platform it has no build for rather than failing an install that already put two binaries in place; asking for it by name there still says so. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * install.sh: clean each component's temp directory as it finishes The EXIT trap is per-process, so installing more than one component left every extraction but the last behind. Cleaning at the end of the function keeps the trap for the paths that exit early. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm
