Integrate framework changes for plugin registration

[saintmatthieu]

On MacOS, a child process inherits the exception ports from its parent. This means that, although diagnostics are disabled for the plugin-registration process, a plugin crashing the app still brings the "MuseScore Studio quit unexpectedly". (At least I assume it does - this happened to us in Audacity.) I think MSS's Sentry might also be getting events for failing plugin registrations on mac because of this, which isn't intended.

This PR uses functionality recently introduced in the framework to disable the forwarding of crash reports to the system handler.

📝 Walkthrough

Walkthrough

The muse submodule pointer is updated to a new commit. MuseScoreCmdOptions adds crash-dump directory and server URL options. The command-line parser reads these hidden options. Diagnostics modules are registered before the audio module when enabled. MuseScoreConsoleApp applies the crash-dump settings and disables system crash reporter forwarding in AudioPluginRegistration mode.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 32f0c

A malformed crash-dump option can cause plugin registration to be skipped. Validate option values before merging.

Warning: On Unix, this list is built from the argc and argv parameters passed to the constructor in the main() function.

On Windows, the list is built from the argc and argv parameters only if modified argv/argc parameters are passed to the constructor. In that case, encoding problems might occur. ... Otherwise, the arguments() are constructed from the return value of GetCommandLine(). As a result of this, the string given by arguments().at(0) might not be the exact program used to start the application on Windows.

Reject an option token as a crash-dump value.

QCommandLineParser consumes the next token as the value for a value-taking option, even when that token starts with -. Therefore, --crash-dumps-dir --register-audio-plugin plugin.vst3 stores --register-audio-plugin as the directory. m_parser.isSet("register-audio-plugin") then remains false, so AudioPluginRegistration mode is not selected.

Validate the raw arguments before parsing, or require the --option=value form when a value starts with -. Also handle the false result from parse() for missing values.
