feat(control_tree): Phase 131 P1.5-P2 DirectValue exit reconnection
Implement DirectValue mode for Normalized shadow exit handling:
**P1.5 Changes**:
- Add ExitReconnectMode::DirectValue (skip exit PHI generation)
- Carry remapped_exit_values through merge result
- Update host variable_map directly with exit values
- Fix loop(true) { x = 1; break }; return x to return 1 correctly
**P2 Changes**:
- Normalize k_exit continuation entry/exit edges
- Rewrite TailCall(k_exit) → Jump(exit_block) for proper merge
- Add verify_all_terminator_targets_exist contract check
- Extend ExitLineReconnector to handle DirectValue mode
**Infrastructure**:
- tools/build_llvm.sh: Force TMPDIR under target/ (EXDEV mitigation)
- llvm_exe_runner.sh: Add exit_code verification support
- Phase 131 smokes: Update for dev-only + exit code validation
**Contracts**:
- PHI-free: Normalized path uses continuations only
- Exit values reconnect via remapped ValueIds
- Existing patterns unaffected (既定挙動不変)

feat(control_tree): Phase 131 normalized loop(true) break-once builder (dev-only)
Implement Normalized shadow builder for loop(true) break-once pattern:
**New Module** (407 lines):
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs
- LoopTrueBreakOnceBuilderBox: loop(true) { <assign>* ; break } lowering
- PHI-free: env parameters + continuation-passing style
- Generated structure: main → loop_step → loop_body → k_exit
- Scope: Bool(true) literal condition only, break at end only
**Integration**:
- src/mir/control_tree/normalized_shadow/builder.rs
- Added lower_with_loop_support() for loop patterns
- try_lower_if_only() now falls through to loop support on capability reject
- src/mir/control_tree/normalized_shadow/mod.rs
- Module declaration added
**Contract**:
- Accepted: loop(true) { <assign of int literal/var/add>* ; break }
- Rejected (Ok(None)): continue, return in body, nested control flow
- Out of scope: general loop conditions, complex post-loop statements
**Limitations**:
- Structure-only (dev-only observation mode)
- Execution path not yet wired (follow-up phase required)
- Shadow JoinModule generation working, structural verification passing
- Unit tests: 1155/1155 PASS

feat(control_tree): Phase 126 AvailableInputsCollectorBox
- Collect available_inputs from function params + CapturedEnv (SSOT)
- BTreeMap for deterministic order
- Box-first modularization with unit tests (5 tests PASS)
- Source priority: params > CapturedEnv
- No AST inference (only pre-computed sources)
