fix: bench mark triggers

[ErnestM1234]

fix benchmark behaviors

• allow to write warnings to PRs
• fix triggers

Greptile Summary

This PR fixes the benchmark workflow triggers by making two configuration changes: adding the pull-requests: write permission required for the benchmark action to post comments, and restricting benchmark data persistence to only occur on automated repository_dispatch events (releases). The previous logic used != 'pull_request' which also allowed manual workflow_dispatch triggers to persist data, while the new logic explicitly allows only repository_dispatch events.

Confidence Score: 5/5

• This PR is safe to merge with no risk - it's a simple workflow configuration fix
• The changes are minimal and well-scoped: adding a required permission and making the persistence logic more restrictive (only on releases). Both changes improve the workflow's behavior and security posture without introducing any risks
• No files require special attention
