   ## Summary
   
   - Exclude the empty `NONE` option from the Fuzzy Match algorithm dropdown so 
the first selectable row is a real algorithm.
   - Declare the measure value field as Integer for Damerau-Levenshtein and 
Needleman-Wunsch (same as Levenshtein), matching the Long distance written at 
runtime and avoiding the `Long` vs `String` type error when storing execution 
data.
    ``` text
   2026/08/07 22:25:14 - demo_fuzzymatch - measure value String : There was a 
data type error: the data type of java.lang.Long object [5] does not correspond 
to value meta [String] (through reference chain: 
org.apache.hop.execution.ExecutionData["rowsBinaryGzipBase64Encoded"])
   ```
   - Simplify `FuzzyMatchMeta` (including `Algorithm` and `FMLookupValue`) with 
Lombok `@Getter` / `@Setter`.
   - Add a unit test asserting distance algorithms expose an Integer measure 
field.
