Anki 25.07

What's new in this version:

New Launcher:
The way Anki is packaged and distributed has changed:
- You can use the launchers below to download the latest Anki version, and update to newer versions/downgrade to old ones
- You'll find a Tools>Upgrade/Downgrade menu item inside Anki to return the launcher
- The oldest supported Anki version to install is 2.1.50
- The Mac and Linux launchers support both AMD64 (Intel) and ARM64 (Apple Silicon) machines. The Windows installer is AMD64-only, but will run in emulation mode on ARM Windows.
- On Linux, glibc 2.36 or later is now required
- Anki now ships with Python 3.13 (but has not yet bumped the minimum Python from 3.9)
- The new launcher still has room for improvement

Notable FSRS/Scheduling changes:
- FSRS-6 brings further algorithm improvements
- Add "grade now" action
- Support load balance and easy days when rescheduling
- Support load balance and easy days in FSRS simulator
- Add a 'max interval too low' warning.
- The optimizer uses a better approach for evaluating optimizations
- The Evaluate button has been replaced with an optional health check that runs during optimization
- #4068 and #4047. If you wish to keep using the old evaluate, you can show the button with a debug console command: #4149.

- Desired retention warning improvements
