feat(train): Halkyon Train's shell, Todo's copied and renamed (ADR 0030, D12)
apps/train with halkyon_train_server, _client and _flutter, as Todo's:
halkyon_base configured by trainBase(), its own register alone and a
member of the instance's where the operator names one, the app on
halkyon_app's gates with Train's frame, account sheet and About, texts
in British English and German that speak of workouts, app.halkyon.train
on Android, iOS, Linux, macOS and Windows.

Where it differs from Todo: development ports of its own (8180 to 8190),
so it runs beside Learn's server; one initial migration with the schema
Todo's migrations end at (the same tables, compared line by line), not
Todo's seventeen; and Todo's icon as a placeholder until the icon tool
of ADR 0031 draws Train's bike. The workspace, the licences, the READMEs
and AGENTS.md name it.

The servers and the module build on Serverpod's core, which is under the SSPL, and so are
under it too. The apps and the shared Flutter packages link only permissively licensed
packages (Todo's and Train's icons are Lucide's, under the ISC licence, whose notice each app registers), and the client packages are generated from our own model definitions, so all of
them are under the AGPL. The curator depends on neither a server nor Serverpod: Learn's
server reads the files it writes, never its code.
Everything else in this repository (tooling, documentation, deployment files) is under
`AGPL-3.0-or-later` unless a file says otherwise.
