Pull request overview
This pull request hardens the repository’s automation by pinning all GitHub Actions to immutable commit SHAs and standardizing the Dependabot configuration to reduce PR noise and align schedules/groups with other repositories.
Changes:
- Pinned all workflow
uses:references to full commit SHAs (with the intended version retained as a trailing comment). - Standardized Dependabot update cadence to monthly for npm, GitHub Actions, and Docker with a flat 7-day cooldown.
- Simplified Dependabot grouping (single catch-all group per ecosystem, including Docker) to consolidate update PRs.
