Also, the introduction of buffered writing improves performance and efficiency when saving these reports to disk.

What

• tools/flakeguard/cmd/aggregate_results.go:
  • Removed saving the aggregated report and filtering failed tests until after logs are removed from the aggregated report's test results.
  • Added removal of logs from test results in the aggregated report before saving, improving clarity and size of the saved report.
  • Reordered operations to save the aggregated report without logs after the logs have been removed, ensuring a more concise and relevant report.
• tools/flakeguard/reports/io.go:
  • Added bufio package to use buffered writing, enhancing file writing performance.
  • Modified SaveReport function to use os.OpenFile with truncation mode and a buffered writer, improving efficiency and handling of file saving operations.
