fde0f6fccb fix: read dependency entries declared in object form (#123)
* fix: read dependency entries declared in object form

The manifest schema lets a dependency entry be an object carrying the name alongside the constraints an installer resolves it by, but every reader took the element as a plain string and skipped what came back empty, so an object entry disappeared: the module it names was left out of the generated LogosModules aggregate, and every call through it failed to compile.

The rule lives in one place now, since the copies of it are how the gap spread. It ships in share/lidl-frontend alongside the parser that includes it, which consumers compile from there.

* fix: read every dependency entry through one pass over the array

The object form reached the umbrella's members and constructor but not its
includes: that emitter still read each element as a plain string, so a module
declared in object form came out as a member whose type was never included, and
the aggregate no longer compiled. It is the Qt-free umbrella, which is what
every universal core module and every cdylib module generates, so the form the
previous commit set out to support failed there in a new way rather than
working.

Reading the array element by element is what let one pass disagree with the
next, so no reader does that any more: dependencyNames() answers what an array
declares, once, and the emitters walk names. That leaves the entry form knowable
in exactly one place, and the includes and members of an aggregate can no longer
be built from different answers.

The umbrella emission moves to generator_lib alongside the per-module wrapper
emitters it mirrors, returning the text instead of writing it, so what it
generates can be asserted on directly; main.cpp writes what it returns. Output
for string-form dependencies is byte-identical in both API styles, with and
without interface dependencies.

The listing mode (`--metadata` with no `--module-dir`) went the same way — it
was the last reader still deciding on its own.
