/**
 * @brief cURL write callback that parses HTTP/1.1 chunked transfer-encoded data.
 *
 * This callback is invoked by the downloader whenever a new block of bytes is
 * received for a request that uses HTTP/1.1 chunked transfer encoding. It
 * implements an incremental parser driven by a state machine stored in
 * CurlCallbackContext::m_ChunkedTransferState. The parser consumes the input buffer,
 * interpreting chunk-size lines, chunk payload, and the required CR/LF
 * delimiters as defined by the HTTP/1.1 Chunked Transfer Protocol.
 *
 * The state machine transitions between:
 * - READING_CHUNK_SIZE: parse the hexadecimal chunk size from the stream.
 * - PENDING_CHUNK_START_LF: wait for the LF that terminates the chunk-size line.
 * - READING_CHUNK_DATA: consume exactly the announced number of data bytes for the current chunk and deliver them to the underlying consumer.
 * - PENDING_CHUNK_END_CR: wait for the CR after a chunk's payload.
 * - PENDING_CHUNK_END_LF: wait for the LF that completes the CRLF sequence after a chunk.
 *
 * The function may be called multiple times with partial chunk boundaries; it
 * maintains parsing progress across invocations via the transfer-state fields
 * in the provided context.
 *
 * @param[in] ptr       Pointer to the buffer containing newly received data.
 * @param[in] numBytes  Number of valid bytes available in @p ptr.
 * @param[in] userdata  Pointer to the CurlCallbackContext or user data
 *                      associated with this transfer, used to track the
 *                      current chunked-transfer parsing state.
