nyash-codex 287ceca18d feat(joinir): Phase 33-16 Loop Header PHI SSOT with TailCallKind refactoring ...

## Problem
- joinir_min_loop.hako returned 0 instead of expected 2
- Entry block's tail call was redirected to itself (bb4 → bb4 self-loop)
- JoinIR function parameters lack SSA definition when inlined

## Solution
- Distinguish entry calls from back edges using TailCallKind enum
- Entry block (LoopEntry) stays at target, back edges redirect to header PHI
- Added explicit classification: LoopEntry, BackEdge, ExitJump

## Key Changes
- instruction_rewriter.rs: TailCallKind enum + classify_tail_call()
- Renamed is_entry_func_entry_block → is_loop_entry_point (clearer intent)
- loop_header_phi_builder.rs: New module for header PHI generation
- joinir_inline_boundary_injector.rs: Skip loop var Copy when header PHI handles it

## Verified
- joinir_min_loop.hako: returns 2 ✅
- NYASH_SSA_UNDEF_DEBUG: no undefined errors ✅
