- Fix NyashParser import path in vm.rs tests
- Improve BoxCall fallback logic for plugin/builtin methods
- Add proper function existence checks before lowering to Call
This ensures plugin Box methods correctly fall back to BoxCall
when the corresponding user-defined function doesn't exist.

Fixed infinite loop issue in VM by addressing phi node caching problem.
The phi node was caching the initial value and returning it for all
subsequent iterations, preventing loop variable updates.
Changes:
- Created vm_phi.rs module to separate loop execution logic (similar to mir/loop_builder.rs)
- Disabled phi node caching to ensure correct value selection each iteration
- Added LoopExecutor to track block transitions and handle phi nodes properly
- Fixed VM to correctly track previous_block for phi input selection
The VM now correctly executes SSA-form loops with proper variable updates:
- Loop counter increments correctly
- Phi nodes select the right input based on control flow
- Test case now completes successfully (i=1,2,3,4)

- 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.

- 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 5.3 of MIR 35→26 reduction project:
- Replace RefNew with NewBox in MIR builder
- Remove unnecessary Const generation for box types
- Process arguments properly for NewBox instruction
- StringBox special handling maintained with NewBox
Frontend now generates only 26-instruction set compliant MIR.
Build successful with expected deprecation warnings.
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.
