refactor!: decouple Raknet MOTD parsing and response shaping

The previous implementation of the RakNet ping was monolithic, mixing
socket management, raw packet validation, and data transformation into
a single, complex flow.

This refactor introduces a clear, multi-stage
processing pipeline that separates these concerns. The logic is now
broken down into multi-stage pipeline: extracting the MOTD string
from the raw pong packet -> parsing that string into a raw
object -> transforming the raw data into a
user-friendly response object.

Additionally, the socket handling logic is improved
with idempotent cleanup function to prevent resource
leaks or race conditions.

As part of this overhaul, external TypeScript definition (`.d.ts`)
files have been removed in favor of rich JSDoc annotations.

BREAKING CHANGE: The structure of the resolved `BedrockPingResponse`
object has been significantly changed to improve clarity and
consistency.
