Build 26515421

This patch is about lag. It is live now on the default branch.

- Recycling Day: the swing calculation is about twice as fast (564 ms to 272 ms in our benchmark).
- Walls load much faster when a round starts (about 100-300 ms down to 2-4 ms per wall in our test).
- Fixed the hammer briefly looking the wrong way during Recycling Day swings. The error messages it caused in the log are gone too.
- Added a graphics quality setting (Low / Medium / High) and an FPS limit. If the frame rate is low on your first launch, the game lowers graphics one step. You can change it in Settings.

If you still see lag, please tell us in the Discussions along with your PC specs.
