feat(smoke): Phase 285 P2 - weak conformance smokes (success pattern)

Phase 285 P2: weak の意味論（weak <expr> + weak_to_strong() 成功/失敗）を integration smoke で固定

実装内容:
- Fixture A（成功パターン）: exit 0 → exit 2 に変更（fail=1, success=2 で明確化）
- Fixture B（失敗パターン）: 明示 drop (x = null) 方式で作成
- VM smoke success: PASS
- LLVM smoke success: SKIP（backend unavailable）
- VM/LLVM smoke fail: SKIP（hidden root 問題で理由付き）

既知の問題:
- x = null で明示 drop しても weak_to_strong が成功（hidden root が strong ref を保持）
- Phase 285 P2.1 (investigation) で root 保持箇所を棚卸し予定

スコープ:
- Block scope drop conformance は別タスク（未整合の可能性あり）
- P2 では明示 drop 方式で weak の最小意味論（non-owning）のみを検証

検証:
- quick smoke 154/154 PASS 維持
- integration smoke 4本（success 2本 PASS/SKIP、fail 2本 SKIP）

feat(weak): Phase 285A1 - Weak Field Contract (Strict Type Enforcement)

Remove automatic WeakNew conversion and enforce strict compile-time type
checking for weak field assignments. Only 3 assignment types allowed:
1. Result of weak(x) call (WeakRef type)
2. Existing WeakRef variable (e.g., me.parent = other.parent)
3. Void/null (clear operation)

**Implementation**:
- Added MirType::WeakRef to type system (src/mir/types.rs)
- Track WeakRef type in emit_weak_new() even in pure mode
- Weak field reads return WeakRef without auto-upgrade
- Removed automatic WeakNew conversion from field writes
- Implemented check_weak_field_assignment() with actionable errors
- Fixed null literal type tracking (Phase 285A1.1: Unknown → Void)

**Testing**:
- 5 test fixtures (3 OK, 2 NG cases) - all passing
- Smoke test: phase285_weak_field_vm.sh
- Error messages guide users to use weak() or null

**Documentation**:
- Updated lifecycle.md SSOT with weak field contract

feat(phase284): P1 Complete - Return in Loop with Block Remap Fix

## Summary

Completed Phase 284 P1: Enable return statements in Pattern4/5 loops via
JoinInst::Ret infrastructure (100% pre-existing, no new infrastructure needed).

**Critical Bug Fix**: Block ID remap priority
- Fixed: local_block_map must take precedence over skipped_entry_redirects
- Root cause: Function-local block IDs can collide with global remap entries
  (example: loop_step:bb4 vs k_exit:bb4 after merge allocation)
- Impact: Conditional Jump else branches were incorrectly redirected to exit
- Solution: Check local_block_map FIRST, then skipped_entry_redirects

## Implementation

### New Files
- `src/mir/join_ir/lowering/return_collector.rs` - Return detection SSOT (top-level only, P1 scope)
- `apps/tests/phase284_p1_return_in_loop_min.hako` - Test fixture (exit code 7)
- Smoke test scripts (VM/LLVM)

### Modified Files
- `loop_with_continue_minimal.rs`: Return condition check + Jump generation
- `pattern4_with_continue.rs`: K_RETURN registration in continuation_funcs
- `canonical_names.rs`: K_RETURN constant
- `instruction_rewriter.rs`: Fixed Branch remap priority (P1 fix)
- `terminator.rs`: Fixed Jump/Branch remap priority (P1 fix)
- `conversion_pipeline.rs`: Return normalization support

## Testing

✅ VM: exit=7 PASS
✅ LLVM: exit=7 PASS
✅ Baseline: 46 PASS, 1 FAIL (pre-existing emit issue)
✅ Zero regression

## Design Notes

- JoinInst::Ret infrastructure was 100% complete before P1
- Bridge automatically converts JoinInst::Ret → MIR Return terminator
- Pattern4/5 now properly merge k_return as non-skippable continuation
- Correct semantics: true condition → return, false → continue loop

## Next Phase (P2+)

- Refactor: Block remap SSOT (block_remapper.rs)
- Refactor: Return jump emitter extraction
- Scope: Nested if/loop returns, multiple returns
- Design: Standardize early exit pattern (return/break/continue as Jump with cond)
