/**
36 
 * Encodes a compact patch command that transforms one word form into another
37 
 * and applies such commands back to source words.
38 
 *
39 
 * <p>
40 
 * The generated patch command follows the historical Egothor convention:
41 
 * instructions are serialized so that they are applied from the end of the
42 
 * source word toward its beginning. This keeps the command stream compact and
43 
 * matches the behavior expected by existing stemming data.
44 
 * </p>
45 
 *
46 
 * <p>
47 
 * The encoder computes a minimum-cost edit script using weighted insert,
48 
 * delete, replace, and match transitions. The resulting trace is then
49 
 * serialized into the compact patch language.
50 
 * </p>
51 
 *
52 
 * <p>
53 
 * This class is stateful and reuses internal dynamic-programming matrices
54 
 * across invocations to reduce allocation pressure during repeated use.
55 
 * Instances are therefore not suitable for unsynchronized concurrent access.
56 
 * The {@link #encode(String, String)} method is synchronized so that a shared
57 
 * instance can still be used safely when needed.
