perf: optimize Docker image size to reduce build failures

Reduce image size from ~1.8GB to prevent GHCR push timeouts and failures.

Changes:
- Add production dependencies stage (--prod flag)
- Remove build tools (make, g++) from runtime image
- Copy only Python scripts from packages/core (not entire package)
- Copy only Typst templates from packages/templates
- Enhance .dockerignore to exclude tests, storybook, build artifacts

Expected benefits:
- 30-50% reduction in image size
- Faster GHCR push times (< 10 minutes)
- Reduced risk of timeout failures
- Same runtime functionality
