v1.0.1 - Pre-built Container Distribution

Changes

• Switched to pre-built container image distribution
• Users now pull images from GHCR instead of building on every run
• Fixed Dockerfile (added unzip package)
• Simplified dependencies to use c7n[azure] bundle
• Reduces workflow runtime from 2-3 minutes to 5-10 seconds

Container Images

• ghcr.io/leftsize/leftsize-action:v1 (major version, auto-updates)
• ghcr.io/leftsize/leftsize-action:v1.0.1 (pinned version)
• ghcr.io/leftsize/leftsize-action:main (latest from main branch)

Policies are embedded in the container for offline operation and version consistency.
