Integration example demonstrating all 10 phases of the Zexus strategic upgrade.

This example shows:
- Phase 1: Modifiers (inline, secure, pure)
- Phase 2: Plugin System (hooks)
- Phase 3: Capability Security (capability checking)
- Phase 4: Virtual Filesystem (sandboxing)
- Phase 5: Type System (type inference)
- Phase 6: Metaprogramming (AST hooks)
- Phase 7: Optimization (profiling)
- Phase 9: Advanced Types (traits)
- Phase 10: Ecosystem (packages)
