A stack can now ship <name>.env and <name>.sh next to its compose files. The hook is sourced with the tag helpers available, which is what the computing .mk files of the catalogue were using make for: 29 of its 44 .mk files only exist to build variables like the fabio tags. Converting stack/host/fabio.mk by hand gives byte-identical output for the route tag, and drops a trailing comma the make version left in the listener list. Also: APP_HOST and APP_URI are computed (the tag helpers build on them), --color controls the escape codes rather than always emitting them, and make test-portability runs the CLI under busybox ash and dash.

# <name>.env dotenv, for plain values
