## DXE Module System
All modules are DXE3 dynamic libraries loaded by dvx.exe at startup.
The loader scans `libs/` for `.lib` files and `widgets/` for `.wgt`
The loader recursively scans `libs/` for `.lib` files and `widgets/` for `.wgt`
files, reads `.dep` files for dependencies, and loads in topological
order. Widget modules that export `wgtRegister()` have it called after
loading.

Individual widget type implementations, each built as a separate `.wgt`
DXE module. The loader scans the `WIDGETS/` directory at startup and

loads every `.wgt` file it finds. Each module exports `wgtRegister()`,
which registers its widget class(es) and API struct with the core.
