Hello everyone!

I got a smallish build for you, this is mostly maintenance and polishing a few more things and merging in some work by other engineers, as my main focus is on Awwdio right now.

There's a new mode for the gradient sky material! And cylinder crop for the Gaussian Splat tool + a bunch of bugfixes and tweaks for it.

A bunch of other fixes too, like the context menu color fixes that @probableprime did, fix for the yt-dlp cookies from browser not working properly and some other improvements.

- Exposed Additive blend mode on GradientSkyMaterial (implemented by @bluecyro, issue #4006)
- Added cylinder crop for Gaussian Splats (requested by @aegis_wolf, @rueshejn, issue #3997)
-- This is available on the Gaussian Splat Tool with visual
-- You can also call this directly on the static asset provider with ProtoFlux

- When drawing a crop shape for Gaussian Splat Tool it is now aligned with the direction you're currently facing
- Gaussian Splat Tool will now automatically update the point cloud colliders on clipped Gaussian Splats
- Changed default stereo separation for photo gesture from 65 mm to 16 mm
-- This generally seems to produce much nicer to look at photos in most situations
-- If your setting was set to 65 mm, it'll be automatically changed to 16 mm. This is so users who haven't touched existing setting have better value. You can change it back to 65 mm afterwards if you prefer.
- Updated yt-dlp from 2025.03.27 to 2025.03.31
- Added mechanism to auto-register settings on startup, to ensure that commonly used settings will always show up (based on request by @nytra, issue #3822)

- Merged Finnish locale update by @airride91
- Merged Korean locale update by @mirpasec
- Merged German locale update by @muppeq
- Merged Japanese locale update by @.aesc
- Merged Chinese locale update by modimobeikete
- Merged French locale update by @j4.lc

- Resolved conflicting sources of color for context menu items on many standard tools that was causing large amounts of log lines (reported by ko-tengu, issue #4008, fixed by @probableprime)
- Fix static asset providers with freshly changed URL indicating that the asset is available before the previous asset is unloaded
-- This fixes some timing issues - e.g. when processing function updates the URL and the updates asset is attempted to be processed - this would previously use the previous asset, rather than the new one
- Tweaked compute buffer layout when uploading gaussian splat data to potentially fix crash on AMD cards with certain quality settings (based on report by @zyro1331, issue #3899)
-- Unfortunately I can't test this as I don't have AMD GPU
- Fixed OnAttach() being called when loading asset dependency components (based on report by @stiefeljackal, issue #4012)
-- This fixes legacy instances of FlatLitToon not loading properly
- Fixed legacy instances of Image not loading properly (found in a log from @stiefeljackal, issue #4012)
- Fixed Cookies From Browser option for yt-dlp not working correctly (reported by @zangooseoo, ikubaysan, @h33t, @forgottensin, issue #3800)
- Fix "Save Screenshot" option not showing/hiding properly in some cases
-- The option will now show for custom-captured items by the user (e.g. custom cameras)
-- The option will be properly hidden when spawning screenshots that are already saved on your account

A quick hotfix for The Truth.

Compatible with previous build, but not updating will allow for falsehoods to spread!

- Reaffirmed The Truth in face of varying capitalization (reported by @dustysprinkles, issue #4031)
