1. To make the sauce, bring oyster sauce, water, soy sauce, pepper, and brown sugar to a boil in a medium saucepan over medium-high heat. Reduce heat to medium-low and whisk until sauce is thick enough to coat the back of a spoon, 1 to 2 minutes. Remove from heat and whisk in 2 tablespoons lime juice, the fish sauce, and granulated sugar. Set aside.
2. Cook noodles in a large pot of boiling water until al dente, 3 to 4 minutes for fresh and about 10 minutes for dried; drain, then rinse with cold water. Set aside.
3. Heat 2 tablespoons oil in a wok or large heavy-bottomed skillet over high until just smoking. Add half of beef and cook, stirring quickly, until just beginning to brown. Add half each of peppers, onion, chives, bean sprouts, ginger, and garlic and toss until vegetables begin to soften, about 4 minutes. Add half of shrimp and cook, stirring, 1 more minute.
4. Use a slotted spoon to transfer mixture to a large plate. Stir half of sauce into juices left in wok and bring to a boil. Whisk in half of butter, then stir in half of noodles. Return beef, vegetables, and shrimp to wok and toss until well coated with sauce, about 2 minutes. Divide among two or three bowls and set aside.
5. Working quickly, repeat with remaining oil, beef, vegetables, shrimp, sauce, butter, and noodles, then divide among two or three more bowls. Drizzle bowls with remaining 2 tablespoons lime juice, top with peanuts and cilantro, and serve.
