Smarter placement for ties

Your idea

MuseScore 4.2 brings the wonderful new options for inside and outside tie placement! While these two options are great, currently the user has to select either one or the other to be the default setting for the entire score.

This is suboptimal because neither option is ideal in many common situations. Therefore, the following system would be a substantial improvement:

For chords of 1-2 notes, use outside placement

For chord of 3 notes or more, use outside placement on the outside notes, and inside placement within

If 2 or more voices are visible, only use outside placement on the outermost notes

Problem to be solved

This would save a lot of time spent manually adjusting ties according to these criteria.

Additional context

If the placement property was exposed to plugins this would be a quick and easy fix as well

Start by tracing the existing inside/outside tie placement options in MuseScore 4.2 and reviewing how the placement property is exposed to plugins. Compare the behavior against the three chord and voice cases described in the issue; done means the automatic rules work without manual adjustment and are covered by relevant tests.
