- Added Store instruction generation in build_assignment()
- This partially addresses the VM infinite loop issue
- However, the loop still uses old values (%0) instead of updated values
- Need to implement proper SSA phi nodes for loop variables
The root cause: MIR generation doesn't properly track variable updates
in loops. Current SSA implementation lacks phi nodes.

- Discovered that nyash.toml already contains comprehensive type information
- Shifted strategy from new BID YAML files to extending existing nyash.toml
- Updated Phase 9.8 plan to integrate with Phase 9.9 permissions model
- Set goal: FileBox working on VM backend with permission controls
- Documented the revolutionary discovery that simplifies the entire approach
This change reflects the strategic decision to leverage existing infrastructure
rather than creating new file formats, making the system more maintainable.

- Fix MIR builder to handle built-in Box types (IntegerBox, StringBox, etc.) specially
- Generate MIR with actual constant values instead of ref_new instructions
- Enhance LLVM mock compiler with MIR interpreter foundation
- Add value storage HashMap for future MIR instruction interpretation
This enables proper MIR generation where 'new IntegerBox(42)' becomes '%0 = const 42'
instead of '%0 = ref_new "IntegerBox"'. This is essential for future LLVM code generation.
Example MIR improvement:
Before:
%1 = const "IntegerBox"
%0 = ref_new %1
After:
%0 = const 42

🎊 Phase 9.75g-0 COMPLETE - Revolutionary Plugin System Achievement\!
✅ Major Completions:
- plugin-tester type validation: nyash.toml integration & method signature verification
- Duplicate method name detection: Enforces Nyash no-overloading policy
- Comprehensive developer guide: 200+ line technical documentation
- Memory safety: HostVtable lifetime issues resolved with LazyLock
- Type information system: External nyash.toml configuration eliminates hardcoded conversions
🚀 Revolutionary Impact:
Nyash now supports dynamic Box type extension via plugins:
```nyash
local file = new FileBox() // Plugin-provided
local db = new PostgreSQLBox() // Future: Plugin-provided
local gpu = new CudaBox() // Future: Plugin-provided
```
📊 Technical Achievements:
- plugin-tester: 4 comprehensive validation modes (check/lifecycle/io/typecheck)
- BID-FFI Protocol: Production-ready with valgrind-verified memory safety
- Type conversion: Automatic string→bytes mapping via nyash.toml
- Method validation: Prevents overloading conflicts in plugin development
🎯 Next Priority: Phase 8.6 VM Performance Improvement
Current issue: VM is 0.9x slower than interpreter (regression\!)
Target: 2x+ speedup for practical VM execution

🚨 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

- Enhanced plugin metadata API with find_method() and get_methods()
- Implemented generic plugin method calling system (execute_plugin_method_generic)
- Fixed TLV encoding: use Bytes tag for string data in write()
- Fixed read() method: provide default size argument when called without args
- Replaced hardcoded execute_plugin_file_method with dynamic system
- Full end-to-end test successful: FileBox plugin write/read working
