macOS users using Colima instead of Docker Desktop were hitting
missing buildx errors and had no documentation to guide them.
Add Colima as a supported Docker runtime, document buildx
installation, and ensure setup-local installs buildx automatically.

Add comprehensive documentation for local development deployment:
- Docker Desktop resource configuration (CPU, memory, disk)
- Common errors and solutions (resource insufficiency, pending pods, GHCR auth)
- Resource expectations table for different memory allocations
- macOS ARM64 (Apple Silicon) notes
- Verification steps and useful debugging commands
Also update env.template with inline comments explaining minikube resource
settings and their relationship to Docker Desktop resources.
