nyash-codex b822355431 docs: Phase 129 progress report (P0-P3 complete)
## Completed 

P0: LLVM EXE smoke test for Phase 128
- VM+LLVM parity verified
- Regression tests pass (phase103, phase118, phase128)

P2: Post-if return var fixture + VM smoke
- phase129_if_only_post_if_return_var_min.hako
- Tests join_k env merge pattern
- Currently passes via fallback (non-Normalized)

P3: Documentation complete
- README.md: Goal, design, scope
- P1-implementation-plan.md: Detailed refactoring plan
- PROGRESS.md: This report

## In Progress 🔄

P1: Materialize join_k continuation
- Status: Analysis complete, awaiting user decision
- Options:
  - A: In-place (fast, risky)
  - B: Phased (recommended, safe)

## Test Results 

- cargo test --lib: 1165 passed
- phase128 VM: PASS
- phase128 LLVM EXE: PASS
- phase129 VM: PASS (fallback path)
- Regression: ALL PASS

## Feedback

Box-First:
- JoinKBuilder module proposed (join_k generation)
- EnvBuilder future consideration

Fail-Fast:
- verify_normalized_structure proposed
- verify_branch_is_return_literal too restrictive

Legacy:
- Phase 123-124 lower_if_node incomplete
- Placeholder logic in lhs_vid resolution

## Next Steps

Awaiting user/ChatGPT decision on Option A vs B
