chore: trigger CI on new commit f932d710

- Run golangci-lint: bump step timeout 5m→45m (command already had 60m
  internal timeout). golangci-lint ran 22+ minutes before failing; the
  5m step timeout was not enforced so it completed naturally with errors.
- go test: add explicit 60m step-level timeout (previously only the
  command-level 60m timeout existed; step-level timeout ensures clean
  failure vs OOM-kill). Retry with -p 1 on first attempt failure to
  handle memory pressure on cold disk I/O.
- golangci-lint command: bump --timeout 40m→60m to match step ceiling.
