Description

It is not clear the semantics of `//collision/surface/bounce/restitution_coefficient` . The current docs are:
> Bounciness coefficient of restitution, from [0...1], where 0=no bounciness.

Beside the math definition of `restitution_coefficient`, what is missing is how the `restitution_coefficient` of two collision in contacts get computed.

Research direction

Start by reviewing the existing documentation for `//collision/surface/bounce/restitution_coefficient` and the related PRs #139 and #30. Trace how restitution coefficients from two colliding contacts are combined, then update the documentation to explain both the mathematical definition and the contact-combination semantics.
