Phase 9.78h: Stabilize MIR26 pipeline

Browse Source 
- Add lib test to sync Core Instruction names with docs (INSTRUCTION_SET.md)
- Optimizer: Pass 0 normalizes legacy ops -> unified (TypeCheck/Cast->TypeOp,
  WeakNew/WeakLoad->WeakRef, BarrierRead/Write->Barrier)
- Optimizer: diagnostics for legacy ops; forbid via NYASH_OPT_DIAG_FORBID_LEGACY=1
- Runner: treat diagnostics (unlowered/legacy) as fatal when enabled
- Printer: unify legacy print style to TypeOp/WeakRef/Barrier
- Verifier: treat Phi inputs correctly (skip merge/dominance violations for Phi)
- Docs: update PHI_NORMALIZATION_PLAN; CURRENT_TASK: add risk note for op duplication
- Misc: PHI debugging/logs kept stable; snapshots still green
