Simplify overview apps workflow to commit directly to main branch

[oblomov-dev]

Summary

Refactored the GitHub Actions workflow for generating overview apps to commit changes directly to the main branch instead of creating pull requests.

Key Changes

• Removed pull-requests: write permission (no longer needed)
• Replaced peter-evans/create-pull-request action with native git commands
• Changed workflow to commit directly to the standard branch instead of creating a separate PR branch
• Added conditional check to skip commit if there are no changes to commit

Implementation Details

The workflow now:

1. Configures git user identity for the bot
2. Stages changes to src and README.md
3. Only commits and pushes if there are actual changes (using git diff --staged --quiet)
4. Pushes directly to the standard branch via HEAD:standard

This simplifies the automation by eliminating the intermediate pull request step while maintaining the same end result of updating the repository with regenerated overview apps.
