mod: example shows how dynamic sizing is achived that can be independent form the reported terminal size
...
Setting the cursor with the `Direct` handler will cause the rendering
to halt at that point and leave the cursor at point.
Due to not enabling *raw mode* with the newly introduced `App.start`
configuration options corresponding inputs are only visible to `zterm`
once the input has been completed with a newline. With this it is not
necessary for the renderer to know nothing more than the width of the
terminal (which is implied through the `Container` sizes). Making it
very trivial to implement.

configured (hence it is currently all commented out for testing).

This should be the way it should be done all the time, such that you
are not rendering for every input, but instead handle all `App.Event`s

similarities with the continuous event loops, which also batches

...
Zig Project Action / Lint, Spell-check and test zig project (push) Successful in 1m2s
Now the `App` contains a state which is a user-defined `struct` which
is passed to the `handle` and `contents` callbacks for `Container`'s and
`Element`'s. Built-in `Element`'s shall not access the `App.Model` and
should therefore never cause any side-effects.
User-defined events shall be used to act as *messages* to cause
potential side-effects for the model. This is the reason why only
the `handle` callback has a non-const pointer to the `App.Model`. The
`contents` callback can only access the `App.Model` read-only to use for
generating the *view* (in context of the elm architecture).

mod: bump zg dependency version
...
Zig Project Action / Lint, Spell-check and test zig project (push) Failing after 26s
As the dependency is still using version 0.14.0, it still causes an
error during testing. Corresponding examples are still working as
expected.

add(continous): example which provides a fixed render schedule
...
The other examples did rendering based on events, which this renderer
does not. This makes these applications potentially not that efficient,
but allows for consistent frame times that make animations, etc.
possible. This example serves to show that you can use `zterm` for both
types of render scheduling and even change between them without much
efford.
