* chore: update plan with cur_path and side constraints requirements

* Refactor: rename int_constraint to constraint, remove int_constraint_kind enum

- Rename int_constraint struct to constraint with fields fml/dep
- Remove int_constraint_kind enum; pre-build formula expressions instead
- nielsen_edge: add_side_int/side_int() -> add_side_constraint/side_constraints()
- nielsen_node: add_int_constraint/int_constraints() -> add_constraint/constraints()
- nielsen_graph: mk_int_constraint(lhs,rhs,kind,dep) -> mk_constraint(fml,dep)
- Remove int_constraint_to_expr (no longer needed)
- search_dfs/simplify_and_init/check_int_feasibility/check_lp_le: drop cur_path param
- Add m_cur_path member to nielsen_graph; m_cur_path.reset() in solve()
- Add get_path_leaf_side_constraints() implementation
- Update seq_parikh.h/cpp and seq_nielsen_pp.cpp to use new constraint API
