- Fixed me ValueId inconsistency in static box methods
- Previously, each me reference generated a new const __me__ ValueId
- Now caches the first me ValueId in variable_map for reuse
- This ensures RefSet and RefGet operate on the same object
- ArrayBox get/set/push now working correctly in VM mode
- Test results: 1, 42, 3 (as expected)
🔧 Technical Details:
- build_me_expression() now stores fallback ValueId in variable_map
- Subsequent me references reuse the same ValueId
- VM BoxCall debug logs confirm ArrayBox methods dispatch correctly

Fixed the method ID order in HttpRequestBox configuration to match plugin implementation:
- path: method_id 1 (was incorrectly 2)
- readBody: method_id 2 (was incorrectly 3)
- respond: method_id 3 (was incorrectly 1)
This resolves the 45-day debugging issue where req.respond(resp) was calling
the wrong plugin method, causing HTTP responses to have empty bodies.
All E2E tests now pass:
- e2e_http_stub_end_to_end ✅
- e2e_http_multiple_requests_order ✅
- e2e_http_post_and_headers ✅

- Add internal access tracking to distinguish me.field from external.field access
- Interpreter correctly allows methods to access their own private fields
- VM tracks object class context during method calls for visibility checks
- Fix VM nested box declaration collection in collect_box_declarations
- Both interpreter and VM now pass all visibility tests consistently
Test results:
- visibility_ok.nyash: ✅ Internal private access allowed in methods
- visibility_error.nyash: ✅ External private access correctly blocked
- All private fields accessible from within their own methods
- Public fields remain accessible from anywhere

## Major Features Added
### Field Visibility System
- Added `private { ... }` and `public { ... }` blocks in box declarations
- Default visibility is now handled explicitly (fields must be in either block)
- Visibility checks enforced at both interpreter and VM levels
### Parser Enhancements
- Extended AST with public_fields and private_fields vectors
- Added parsing for visibility blocks in box definitions
- Maintained backward compatibility with existing `init { ... }` syntax
### Interpreter Implementation
- Added visibility checks in field access (get_field/set_field)
- External access to private fields now throws appropriate errors
- Internal access (within methods) always allowed
### VM Implementation
- Extended VM with object_class tracking for visibility checks
- RefGet/RefSet instructions now enforce field visibility
- Fixed nested box declaration collection (boxes defined inside methods)
### Test Examples Added
- docs/examples/visibility_ok.nyash - demonstrates correct usage
- docs/examples/visibility_error.nyash - tests private field access errors
## Technical Details
### Error Messages
- Interpreter: "Field 'X' is private in Y"
- VM: Same error message for consistency
### Current Limitations
- All RefGet/RefSet treated as external access in VM (internal flag future work)
- Legacy `init { ... }` fields treated as having unspecified visibility
## Test Results
✅ Interpreter: Both test cases pass correctly
✅ VM: Both test cases pass correctly after nested declaration fix
This implements the foundation for proper encapsulation in Nyash,
following the "explicit is better than implicit" philosophy.

- 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)

Phase 5.2 of MIR 35→26 reduction project:
- VM backend: Reject all 17 deprecated instructions with proper error messages
- WASM backend: Reject deprecated instructions with migration guidance
- All deprecated instructions now properly handled in both backends
- Build successful with expected deprecation warnings
Deprecated instructions removed:
- UnaryOp → Use BinOp
- Load/Store → Use BoxFieldLoad/BoxFieldStore
- ArrayGet/ArraySet → Use BoxFieldLoad/BoxFieldStore or intrinsics
- Print/Debug → Use Call @print/@debug
- TypeCheck/Cast → Use Call @type_check/@cast
- Throw/Catch → Use Call @throw/@catch
- RefNew → References handled implicitly
- BarrierRead/BarrierWrite → Use AtomicFence
- FutureNew/FutureSet/Await → Use NewBox/BoxCall
- Copy/Nop → Not needed in final IR
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.
