Detailed Description

Wraps FunctionalWeakForm to provide TimeInfo (time, dt, cycle) to integrands instead of just time.

This class provides a thin wrapper around FunctionalWeakForm that automatically converts the time parameter into a TimeInfo struct containing time, timestep size (dt), and cycle number. This allows physics systems to access timestep information needed for time integration.

Key features:

• All integrands receive TimeInfo instead of just time
• Systems are responsible for manually applying time integration rules
• Supports body integrals, boundary integrals, boundary fluxes, and interior boundary integrals
• Default behavior passes ALL input fields to integrands (can be overridden with DependsOn)
