feat: the apps' icons as one family, drawn by one tool (ADR 0031)
tool/app_icons.py at the root replaces Learn's and Todo's scripts: each
app's Lucide glyph (lucide-static 1.50.0) drawn by librsvg, fading from
cobalt through the colours ADR 0031 names, then every platform's
launcher icon through flutter_launcher_icons, Windows' .ico with every
size, and Learn's snap icon.

Learn's icon becomes the graduation cap, its window's on Linux too, with
Lucide's notice in its licence list; the kingfisher stays the emblem on
the rail and the launch screen. Todo's becomes list-todo, Train's bike.

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 (the apps' 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.
