Pull Request Overview

Adds a Pyomo-based adapter for OMMX v1 instances, with full solve, decode, and error‐handling support. It also includes comprehensive integration and error tests, plus project metadata and task automation.

• Implement OMMXPyomoAdapter with variable, objective, and constraint mapping, plus solve/decode logic
• Add integration tests covering LP, MILP, binary, maximize, constant, quadratic objectives/constraints
• Add error tests for unsupported objectives/constraints, solver availability, and infeasible constants
• Configure project metadata (pyproject.toml) and automation tasks (Taskfile.yml)

• [nitpick] The parameter name 'generater' is misspelled; consider renaming it to 'generator' for clarity.

decode_to_state expects SolverResults, not a Pyomo model; store the solver result in a variable and pass it to decode_to_state (e.g., results = solver.solve(model); state = adapter.decode_to_state(results)).

Suggested change

	solver.solve(model)
	# check objective
	assert pyo.value(model.objective) == 0
	state = adapter.decode_to_state(model)
	results = solver.solve(model)
	# check objective
	assert pyo.value(model.objective) == 0
	state = adapter.decode_to_state(results)

This specific error message is raised for missing variable values, but tests expect a generic 'Failed to decode state from results' message. Consider allowing the exception to be caught by the surrounding except block or updating the message format to match test expectations.

Suggested change

	raise OMMXPyomoAdapterError(
	f"Variable {var_name} has no value - model may not be solved"
	)
	entries[var.id] = value
	return State(entries=entries)
	except Exception as e:
	raise OMMXPyomoAdapterError(f"Failed to decode state from results: {e}")
	raise ValueError(
	f"Variable {var_name} has no value - model may not be solved"
	)
	entries[var.id] = value
	return State(entries=entries)
	except Exception as e:
	raise OMMXPyomoAdapterError("Failed to decode state from results") from e
