This PR introduces a new installer and uninstaller for the Windows platform.
Both are written in Rust and compiled to a single executable. The executable has no dependencies (other than what is included in the Windows), links the C++ runtime statically if needed.
The change is motivated by numerous issues with with the `electron-builder`-generated installers. The new installer should behave better, not have issues with long paths and unblock the `electron-builder` upgrade (which will significantly simplify the workflow definitions).
To build an installer, one needs to provide the unpacked application (generated by `electron-builder`) and the `electron-builder` configuration (with a few minor extensions). Code signing is also supported.
This PR updates the Rust toolchain to recent nightly.
Most of the changes are related to fixing newly added warnings and adjusting the feature flags. Also the formatter changed its behavior slightly, causing some whitespace changes.
Other points:
* Changed debug level of the `buildscript` profile to `lint-tables-only` — this should improve the build times and space usage somewhat.
* Moved lint configuration to the worksppace `Cargo.toml` definition. Adjusted the formatter appropriately.
* Removed auto-generated IntelliJ run configurations, as they are not useful anymore.
* Added a few trivial stdlib nightly functions that were removed to our codebase.
* Bumped many dependencies but still not all:
* `clap` bump encountered https://github.com/clap-rs/clap/issues/5407 — for now the warnings were silenced by the lint config.
* `octocrab` — our forked diverged to far with the original, needs more refactoring.
* `derivative` — is unmaintained and has no updated version, despite introducing warnings in the generated code. There is no direct replacement.
This PR updates the build script:
* fixed issue where program version check was not properly triggering;
* improved `git-clean` command to correctly clear Scala artifacts;
* added `run.ps1` wrapper to the build script that works better with PowerShell than `run.cmd`;
* increased timeouts to work around failures on macOS nightly builds;
* replaced depracated GitHub Actions APIs (set-output) with their new equivalents;
* workaround for issue with electron builder (python2 lookup) on newer macOS runner images;
* GUI and backend dispatches to cloud were completed;
* release workflow allows creating RC releases.
