Code Review

This pull request removes the 'dependencies' label from the Dependabot configuration for the GitHub Actions, pip, and npm ecosystems. The reviewer suggests adding a 'groups' configuration for the pip ecosystem to consolidate updates into a single pull request, which would improve maintenance efficiency and ensure consistency with the other ecosystems defined in the file.

The pip ecosystem is currently missing a groups configuration, which is present in all other ecosystems in this file (github-actions and npm). Adding a group for pip dependencies will consolidate updates into a single PR, reducing noise and improving maintenance efficiency. This aligns with the project's mission of high-efficiency technical-log compression and industrial-grade maintenance.
