Replace .find() != .end() with .contains() for cleaner code

* Feature: make 'threads' parameter more prominent (default to max of system) and hide input/output parameters from the Param editor  which are already used in the dropdown menus" of the 'Apply TOPP tool dialog'

* fix typo

* git `Apply TOPP tool`, which could not find output file after the TOPP tool ran.

* use correct output file type to determine annotator; always add a new layer

* fix copying of openms_thermo_bridged.dll to test folder (GENERATOR_IS_MULTI_CONFIG is a property, not a variable; needs translation)

* fix to_path function (could not deal with 'ä' in Filenames); added tests

* fix potential issue with single config generators on Windows (missing target_name); support all muti-config generators on Windows. No just VS

The ubuntu-arm "Create tarball" step wrote OpenMS-<ver>.tar.gz with a
relative path, i.e. into ${{ github.workspace }} -- the same directory it
archives via `-C ${{ github.workspace }} .`. As tar streamed the growing
archive into that directory, GNU tar reported "tar: .: file changed as we
read it" and exited 1, failing the step under `bash -e`. This broke the
nightly matrix deterministically (reproduced on the 2026-06-03..-06 runs).

Write the tarball to ${{ runner.temp }} (outside the workspace) and upload
it from there, so the archived directory no longer changes during the read.
Drop the now-dead self-exclude (the output is no longer in the archived tree).

Fixes OpenMS#9458
