This RFC proposes adding a new slash command /stdlib commands-comment that automatically generates and posts PR-specific build and test commands as a comment from the @stdlib-bot. This will help streamline the PR review process by providing contributors with the exact commands needed to build, test, and benchmark their changes.

The slash command should:

• Automatically detect the package path from the PR's changed files

• Generate the appropriate make commands for:

  • Building native add-ons
  • Running C examples
  • Running C benchmarks
  • Running JavaScript examples
  • Running JavaScript benchmarks
  • Running tests

In the new GitHub actions workflow for this slash command, we will need to Implement logic to:

• Identify changed package paths
• Generate appropriate command strings based on package path
• Format commands in markdown
• Post formatted comment via GitHub API

One open question is how to handle the case when multiple packages are modified in one PR.
