Review Comment:
   `sendRequest` prints failures/exceptions but never fails the script/Gradle 
task. As a result, `./gradlew protectBranches` can exit successfully even if 
protections were not applied (non-2xx responses, auth errors, etc.). Consider 
throwing on non-success response codes and rethrowing exceptions (or 
accumulating failures and throwing at the end) so the task has a reliable 
failure signal.
   ```suggestion
               def errorText = conn.errorStream?.text
               println "FAILED: ${conn.responseCode} - ${errorText}"
               throw new IllegalStateException("Request to ${url} failed with 
HTTP ${conn.responseCode}: ${errorText}")
           }
       } catch (Exception e) {
           println "ERROR: ${e.message}"
           throw e
   ```

Review Comment:
   Same parsing issue as ProtectBranches.groovy: lines in `tableData` begin 
with `||`, so `split("\\|")` yields leading empty tokens and `parts[1]` is 
empty. That makes `branch` empty and the delete request will target an invalid 
ref (`.../git/refs/heads/`). Use `tokenize('|')` / remove empty tokens, or 
update the column index to use the branch value token.
   ```suggestion
       def parts = line.tokenize('|').collect { it.trim() }
       if (parts.size() < 3) return null
   
       def branch = parts[0].replace("origin/", "")
       def type   = parts[2]
   ```

Review Comment:
   `sendRequest` only logs failures/exceptions and continues, so `./gradlew 
deleteBranches` can report success even if some/all branch deletions failed 
(e.g., 404/403). Consider failing the task on non-2xx responses and rethrowing 
exceptions, or at least tracking failed branches and throwing at the end so 
operators can trust the result.
