nyash-codex 78199dc451 docs: Phase 188 Completion Summary - JoinIR Loop Pattern Expansion
Add comprehensive completion summary document for Phase 188 with:

## Content Overview

- Executive summary: 3 loop patterns, infrastructure complete
- Implementation details: 8 files, +523 lines, 5 commits
- Pattern characteristics: Pattern 1/2/3 explanations with examples
- Routing decision tree: Pattern detection and routing logic
- Lowering pipeline: Complete step-by-step conversion process
- Test cases: All 3 patterns with expected outputs
- Known limitations: Select → MIR conversion blocker (Phase 189)
- Future work: Generalization, optimization phases
- Phase 189 next steps: ChatGPT inquiry prepared
- Lessons learned: Box theory, architecture clarity
- Success criteria: All items checked 

## Status Summary

| Pattern | Implementation | Status | Test | Result |
|---------|---|--------|------|--------|
| Pattern 1 | Simple While Loop |  Complete | loop_min_while.hako | Prints 0,1,2 |
| Pattern 2 | Loop with Conditional Break |  Complete | joinir_min_loop.hako | Returns break value |
| Pattern 3 | Loop with If-Else PHI | 🔄 Infrastructure | loop_if_phi.hako | Blocked on Select → MIR |

## Key Achievements

 Unified routing system based on pattern detection
 JoinInlineBoundary solves ValueId remapping cleanly
 Pattern 3 infrastructure complete (lowering + routing)
 Phase 189 inquiry prepared with 7 detailed questions
 Clear documentation for future developers

## Files

- 8 files modified/created
- +523 lines added (features)
- -194 lines removed (refactoring)
- 5 git commits
- 2 test cases passing (1 deferred)
