Review Comment:
   Minor: `containsSecret(s)` now internally calls `redact(s)` and discards the 
result, then `redact(s)` is called again here. Could be simplified to:
   
   ```suggestion
                   if (result instanceof String s) {
                       String scrubbed = redactor.redact(s);
                       if (!scrubbed.equals(s)) {
                           result = scrubbed;
                           wasRedacted = true;
                       }
   ```
   
   This avoids running the full masking pipeline twice for strings that contain 
secrets.
