bd39e09c5d docs: Phase 131 P0 structure implementation complete
Document Phase 131 P0 Normalized loop(true) break-once:

**Documentation**:
- docs/development/current/main/phases/phase-131/README.md (234 lines)
  - Goal: loop(true) { <assign>* ; break } in Normalized (PHI-free)
  - Scope: one-time execution loop only
  - Contract: Bool(true) literal + break at end
  - SSOT: EnvLayout, loop structure contract, VM+LLVM parity
  - Current status: structure implemented, execution wiring pending
- docs/development/current/main/10-Now.md
  - Updated Next section with Phase 131 P0 status

**Deliverables** (P0):
-  Complete loop(true) break-once Normalized lowering logic
-  PHI-free implementation (env + continuations)
-  Box-First modular design
-  Foundation for execution (structure verified)
-  Unit tests passing (1155/1155)

**Known Limitation**:
- Execution path not yet wired (dev-only observation mode)
- Follow-up phase needed to route execution through Normalized shadow
- VM/LLVM smokes fail (expected until execution wiring)

**Next Steps**:
1. Modify try_cf_loop_joinir to check Normalized shadow first
2. Add dev-mode routing for loop(true) break-once
3. Implement JoinModule → MIR merge for loop patterns
4. Enable VM/LLVM smoke tests
