A bugfix release. All three of these came out of one report on a1k.org — thanks to Radiocarbon for a properly detailed one.
LABEL= works on the command line. It was documented in four places and had never been implemented: it was missing from the ReadArgs template, so passing it made ami2ha reject the entire command line and print the usage text. The documented first run now does what the manual says:
ami2ha <host> TOKENFILE=S:ha.token LABEL=amiga WRITECONFIG=S:ami2ha.cfg
A failed start from Workbench now says so. Startup errors went to printf and a console that does not exist on a double-click, so an installation whose host line was still commented out — which is what the installer writes if you skip that prompt — did nothing at all. No window, no message. Those errors now open a requester.
A rejected argument names itself, above the usage text rather than below it. The usage text ends with a line about keeping the access token in a file, so anyone who mistyped an option read that as a token problem and went looking in the wrong place.
Nothing else changed: same features, same dashboard, same configuration format as 0.3. Both a 68000 and a 68020 build are in the archive and the installer picks the right one.
Verified on an Amiga 4000T (68060, AmigaOS 3.2) against a live Home Assistant.
