Walkthrough

This pull request discontinues support for armhf, armv7, and i386 architectures across the project. Changes include narrowing the Renovate configuration regex to only match aarch64 and amd64, removing architecture-specific build configurations, updating runtime configuration to exclude armv7, and removing associated documentation badges.

Changes

Cohort / File(s)	Summary
Build & Runtime Configuration grocy/build.yaml, grocy/config.yaml	Removed armv7 architecture entries from build mappings and architecture list configuration.
CI/CD Configuration .github/renovate.json	Narrowed Renovate regex matchStrings from (aarch64|amd64|armhf|armv7|i386) to (aarch64|amd64) only for Dockerfile update matching.
Documentation README.md	Removed badges for armhf, armv7, i386, alpine-packages, dockerhub, and python-packages.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Context: All changes follow a consistent, straightforward pattern of removing architecture references across configuration and documentation files.
• Areas for attention: Verify that removing these architectures doesn't break any undocumented dependencies or CI pipelines that may still reference them.

Poem

🐰 Hop! We've trimmed the architectures lean,
Keeping only the strongest seen,
aarch64, amd64 stand tall,
Cleaner configs, badges removed from all! 🏗️

15-15: ✓ Correct architecture restriction for Renovate dependency tracking.

The regex pattern now properly restricts dependency version detection to only supported architectures (aarch64 and amd64), preventing Renovate from attempting to update dependencies for dropped architectures. The pattern syntax is valid and aligns with the PR objective.
