Module list_solver 

List variable solver for routing and scheduling problems.

This module provides run_list_solver for problems using list variables (e.g., vehicle routes, shift schedules). The solver configuration (construction type, move selectors, acceptor, forager, termination) is driven by solver.toml.

Logging levels:

• INFO: Solver start/end, phase summaries, problem scale
• DEBUG: Individual steps with timing and scores
• TRACE: Move evaluation details

Functions

run_list_solver

Solves a list variable problem using construction heuristic + local search.
