refactor(skills): reinstall from upstreams, drop skills-lock.json

[devantler]

Re-install each agent skill from its original upstream repo via gh skill install, so every installed SKILL.md now carries metadata.github-* frontmatter pointing at the true origin instead of devantler-tech/skills. gh skill update --all reads that metadata directly, making the sidecar skills-lock.json redundant.

Type of change

• 🧹 Refactor

What changed

• Delete skills-lock.json.
• Reinstall 11 of 12 skills from upstream via gh skill install <owner/repo> <path> --agent github-copilot --scope project --dir .agents/skills.
• Bump .github/workflows/update-skills.yaml to the refreshed reusable workflow and swap the skills-lock input for the new dir input.

⚠️ siderolabs skill dropped temporarily

siderolabs/docs ships its skill as public/skill.md (lowercase), which gh skill install rejects — it only recognises SKILL.md. Until the upstream renames the file (or gh skill gains a case-insensitive fallback), the siderolabs skill has been removed from this repo. Manage it out-of-band if you need it.

Breaking change

skills-lock.json is removed. The siderolabs skill is temporarily unavailable pending an upstream rename to SKILL.md.

Pull request overview

This PR refactors how Copilot agent skills are managed in-repo by removing the skills-lock.json sidecar and switching to upstream-installed skills whose SKILL.md frontmatter points at their real source, aligning with the newer “update from metadata + directory” workflow.

Changes:

• Deleted skills-lock.json and updated the scheduled “update skills” workflow to target .agents/skills directly.
• Reinstalled/updated multiple skills so their metadata.github-* frontmatter references upstream repos/refs instead of devantler-tech/skills.
• Expanded/updated the gitops-knowledge skill content with new references (e.g., Terraform bootstrap, gitless image automation) and refreshed guidance.
