Orkuncakilkaya 20d011f8e9 feat(lang): UI components as files - component Name { ... } beside Name.xml and Name.lss
The compiler turns a component declaration into:
- a record of its props and state;
- a constructor, a props setter, a model and a call;
- a class, registered with ludic.ui at start.

Its template and styles are read from beside it and compiled in, with @import inlined, and a
missing template fails the build.

In the runtime:
- each mounted instance keeps its own props and state, and `set` in a template writes the state;
- styles are scoped to the component;
- class, style and id on a component's tag land on its root, styled by the parent's sheet too;
- ui_reload re-reads a component's files from disk and keeps instances.

The package's own module is now ludic_ui, so a program may call a directory of its own ui.

# reload.ludic - a developer's templates and stylesheets read again when they change on disk: every
# file is re-read in the order it was first loaded (so an import is there before its importer), and
# the screens' state is kept, as React's fast refresh keeps it. True when anything changed.
