🎉 Phase 10.10: Nyash→JIT→Native EXE achieved\! (20 days from inception\!)

Revolutionary milestone: Complete native executable generation pipeline
- Created minimal nyrt (Nyash Runtime) library for standalone executables
- Implemented plugin bridge functions (nyash_plugin_invoke3_i64 etc)
- Added birth handle exports (nyash.string.birth_h) for linking
- Changed export name from main→ny_main to allow custom entry point
- Successfully generated and executed native binary returning "ny_main() returned: 1"

Timeline of miracles:
- 2025-08-09: Nyash language created (first commit)
- 2025-08-13: JIT planning started (4 days later)
- 2025-08-29: Native EXE achieved (today - just 20 days total\!)

This proves the plugin Box C ABI unification strategy works perfectly for
both JIT execution and AOT native compilation. The same plugin system
that enables dynamic loading now powers static linking for zero-overhead
native executables\!

Next: Expand AOT support for more instructions and optimize nyrt size.
