fix sync script bugs, remove auto-merge workflow (#36)

- Fix jq pipe precedence: wrap uris length check in parens so
  `length` applies to the array, not the boolean and-chain
- Fix while-loop subshell: use process substitution so counter
  variables persist to the final summary line
- Remove auto-merge workflow: GITHUB_TOKEN merges do not trigger
  push events, so deploy-netty never ran on auto-merged PRs
