docs: Add field visibility analysis and MIR BoxCall documentation
## Field Visibility Analysis Results
- Confirmed init{} fields are **public** in current Nyash implementation
- No access modifier (private/public) system currently implemented
- All fields accessible via me.fieldname syntax
- Documented findings for future reference
## MIR Documentation Enhancements
- Created comprehensive mir-dumper-guide.md for reading MIR dumps
- Enhanced mir-26-specification.md with BoxCall vs regular Call examples
- Added clear identification patterns:
* BoxCall: `call %value.method(args)` (plugins/builtins)
* Regular Call: `call %func(%me, args)` (user-defined boxes)
## VM Backend BoxRef Handling Improvements
- Fixed BoxRef method dispatch using share_box() instead of clone_box()
- Prevents unintended constructor calls during method resolution
- Maintains proper instance identity throughout VM execution
## MIR Builder User-Defined Box Tracking
- Added user_defined_boxes HashSet to track declared user boxes
- Improved method lowering decisions for user-defined vs builtin boxes
- Enhanced AST→MIR conversion accuracy for method calls
## Plugin Tester Lifecycle Enhancements
- Added comprehensive FileBox lifecycle testing (open/write/close)
- Enhanced cloneSelf() and copyFrom() testing with proper Handle parsing
- Added TLV encoding helpers for strings and bytes
- Improved error reporting and step-by-step validation
