feat: add 1D collision simulation with vector visualization

[AgnibhaDebnath]

🔍 Description

Added a new 1D collision simulation with adjustable mass, velocity, and restitution.

The simulation includes:

• Velocity vector visualization
• Momentum and kinetic energy calculations
• Boundary collision handling
• Trail rendering support
• Responsive layout support

This simulation was designed to help students better understand conservation of momentum and elastic collisions through interactive visualization.

Closes #180

Hey @AgnibhaDebnath well done, it seems good, so i'm going to merge it! I meant originally a simulation with 2d collision (a better version of benchmark one), but this is fine also!
thank you again for this!

Thank you @mattqdev! I’m glad the implementation was helpful. I’d also be interested in exploring a 2D collision version in the future.
