NO-ISSUE: Add /build-iso-builder skill for agent-installer-utils

[rwsu]

This skill builds and pushes the agent-iso-builder container image.

Features:

• Dynamically generates Dockerfile during build
• Uses FROM scratch base (minimal, no subscription needed)
• Requires image tag via --tag parameter
• Optional --authfile parameter for registry authentication
• Optional --push flag to skip interactive prompt and auto-push
• Prompts before pushing to registry
• Shows usage instructions

Usage:
/build-iso-builder --tag image:tag [--authfile ] [--push]

Example:
/build-iso-builder --tag quay.io/myuser/agent-iso-builder:latest
/build-iso-builder --tag quay.io/myuser/agent-iso-builder:latest --authfile ~/.docker/config.json
/build-iso-builder --tag quay.io/myuser/agent-iso-builder:latest --authfile ~/.docker/config.json --push
