/**
 * Shapes an object by picking or omitting specified keys,

 * @template T - Original object type.
 * @template K - Keys to include or exclude (exact literals inferred).
 * @param obj - Object to shape.
 * @param keys - Array of keys (use `as const` for smart typing).
 * @param action - Determines pick or omit, truthy to omit or falsy to pick (default: undefined = pick).
 * @returns A Partial object with exact types.
