nyash-codex ef71ea955c feat(control_tree): Phase 133 P0 - Multiple post-loop assigns support

Extend Phase 132's loop(true) + post-loop to accept multiple assignments:

Goal: `x=0; loop(true){ x=1; break }; x=x+2; x=x+3; return x` → exit code 6

Implementation:
- Extended loop_true_break_once.rs pattern detection (len() == 2 → len() >= 2)
- Added iterative assignment lowering (for loop over post_nodes)
- Reused Phase 130's lower_assign_stmt for each assignment
- Maintained ExitMeta DirectValue mode (PHI-free)

Changes:
- apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase133_*_multi_add_*.sh (new smokes)
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs (+30 lines)
- docs/development/current/main/phases/phase-133/README.md (new documentation)
- docs/development/current/main/10-Now.md (Phase 133 entry added)

Scope (Phase 130 baseline):
- ✅ x = <int literal>
- ✅ x = y (variable copy)
- ✅ x = x + <int literal> (increment)
- ❌ Function calls / general expressions (future phases)

Design principles:
- Minimal change: ~30 lines added
- SSOT preservation: env_post_k remains single source of truth
- Reuse: Leveraged existing lower_assign_stmt
- Fail-Fast: Contract violations trigger freeze_with_hint

Test results:
- cargo test --lib: 1176 PASS
- Phase 133 VM: PASS (exit code 6)
- Phase 133 LLVM EXE: PASS (exit code 6)
- Phase 132 regression: PASS (exit code 3)
- Phase 131 regression: PASS (exit code 1)
- Phase 97 regression: PASS

Architecture maintained:
- 5-function structure unchanged (main/loop_step/loop_body/k_exit/post_k)
- PHI-free DirectValue mode
- Zero changes to ExitMeta, merge logic, or JoinIR contracts
