Improve Skill Tree particle animation performance on low-end devices

[FatBy]

Description

The Skill Tree view uses Canvas 2D particle animation which can drop frames on integrated GPUs or low-end laptops.

Current Behavior

• All particles rendered every frame regardless of device capability
• No frame rate adaptation
• Can cause lag on machines with integrated graphics

Expected Behavior

• Detect low frame rates and reduce particle count dynamically
• Option to disable particle animation entirely in Settings
• requestAnimationFrame properly throttled

Files to Modify

• src/components/blueprint/SkillTreeView.tsx (main animation loop)
• Settings panel for toggle option

Helpful Context

The animation loop is in the useEffect that calls requestAnimationFrame. Look for the particles.forEach block.
