feat(fls): read and write a project's own applications as their beans

A project's own applications (classes under projekt/anwendungen, installed
on a host) are no longer left out. The decoder now keeps the Java type of
every primitive — at setters, constructor and call arguments, also through
shared ids like Integer0 — and which properties an object's own getter
made. beanCapture.ts turns a decoded bean back into what the writer writes,
with the node's system software as a mark the writer replaces by the
system software it writes; what the format cannot say is refused, not
guessed (an unresolved value, a Field, a factory-made object, an object a
getter reaches elsewhere in the file). The reader keeps own applications as
captured beans; the corpus no longer warns.

The capture first took a setter with another object's getter result for an
own getter; the round-trip test found it. The Java oracle did not show
whether an application runs on its node's system software, so a mutation
writing the mark instead survived; it now reports onItsSystem (true for all
192 applications of the corpus).

Checked by Java: from the files written again, FILIUS loads Accumulator and
Broadcast installed, switched on and on their node's system software, as
in the original. The round-trip test covers every primitive, null, a
class, an array, shared objects, getter chains, constructed elements, map
reads and static constants.
