Abdessamad Derraz 34619c778f fix: publish target aliases and refuse an unknown one
The pack builder accepts the aliases declared in the target overrides,
so --target switch works there, but the installer's target manifests
carried only canonical names. The documented word was the one that
failed, and the installer then carried on with every file: 1911 files
and 4.1 GB where the user had asked for the 863 that target needs.

Aliases are emitted beside their canonical target, and an unknown
target now stops the run and lists what is available. A filter is
applied or refused, never ignored.
