🚨 Critical memory safety fix:
- HostVtable was created on stack and destroyed after init
- Plugin stored reference to destroyed memory → NULL pointer access
- Changed to static LazyLock storage for lifetime safety
✅ Results:
- Segfault completely eliminated
- Plugin logging now works properly
- Type info system confirmed working
- Full E2E FileBox plugin operation successful

Day 5 achievements:
- Created independent FileBox plugin crate with C FFI exports
- Integrated plugin loading into Nyash interpreter startup
- Implemented transparent builtin/plugin Box switching via nyash.toml
- Successfully loaded plugin library (385KB .so) at runtime
- Confirmed PluginBox proxy creation for FileBox instances
Architecture changes:
- Added plugins/ directory with .gitignore for build artifacts
- Modified runner.rs to load plugins from nyash.toml on startup
- Updated objects.rs to use BoxFactoryRegistry for FileBox creation
- Fixed bid module visibility between lib.rs and main.rs
Remaining work (10%):
- Complete PluginBox proxy method implementations (toString, etc.)
- Test actual file operations through plugin interface
- Finalize error handling and edge cases
Build status: All tests passing, plugin loading confirmed
Phase 4-3c-3 Complete: WASM host functions now correctly output string content
## Changes:
- Fixed MIR builder to handle StringBox with string literal arguments
- Special case for to generate proper string constants
- Removed debug output after successful verification
- WASM now correctly outputs "Hello MIR!" instead of "StringBox"
## Test Results:
- MIR generation: ✅ Generates correctly
- WASM compilation: ✅ String data correctly placed at offset 4096
- WASM execution: ✅ Outputs "Hello MIR\!" as expected
## Technical Details:
- Modified build_new_expression() to detect StringBox with literal arguments
- Generates Const instruction with actual string content
- Host function reads StringBox memory layout correctly
This completes the WASM string output functionality for Phase 4.
