FPS Tune (Particle + Weather Optimizer)

THIS IS A FULL NEOFORGE RELEASE, ALTHOUGH IT USES A BETA NEOFORGE BUILD, ALL BUGS TO BE REPORTED TO THE NEOFORGE TEAM AND NOT US.

• 🧭 New settings page. It's split into tabs, uses plain wording and explains each trade-off you'll see in game.
• 🎚️ Profiles. Choose Balanced, Smoother frames, Maximum FPS or More particles. If you change any setting yourself, the profile shows as Custom.
• 🔄 Adaptive is its own switch, so you can use it with any profile.
• 📊 Live particle limit. The cap now updates in real time.
• 📏 One distance setting. A single distance controls how far particles are kept.
• 🌧️ Weather mode. Choose Vanilla, Lighter or Off rain and snow.
• ⌨️ F6 feedback. Pressing F6 now shows a message confirming what changed.
• 🎨 Every setting has its own icon, so the settings pages look consistent.
• 🔁 Fixed: the profile button no longer gets stuck on "More particles" and cycles through every profile.
• ⎋ Escape now saves your changes, like vanilla option screens. Use Cancel to discard them.
• 👁️ Fixed: particle distance is now measured from the camera, so it stays correct in third person and spectator view.
• ⚙️ Old config files are upgraded to the new format automatically.
• 📦 Targets: Minecraft 26.3 Fabric, 1.21.11 Fabric and 1.21.11 NeoForge.
