feat(control_tree): Phase 136/137 - return literal and add expression (dev-only)
Phase 136 P0: Return literal (Integer) support
- Extend loop(true) break-once to support `return 7`
- Fixtures: phase136_loop_true_break_once_return_literal_min.hako (exit code 7)
- VM/LLVM EXE parity achieved
Phase 137 P0: Return add expression support
- Extend to support `return x + 2` and `return 5 + 3`
- LHS: Variable or Integer literal
- RHS: Integer literal only
- Fixtures:
- phase137_loop_true_break_once_return_add_min.hako (exit code 3)
- phase137_loop_true_break_once_return_add_const_min.hako (exit code 8)
- phase137_loop_true_break_once_post_return_add_min.hako (exit code 13)
- VM/LLVM EXE parity achieved
Implementation:
- Added lower_return_value_to_vid() method in loop_true_break_once.rs
- Replaced extract_variable_name() with unified return value lowering
- Supported patterns: Variable, Integer literal, BinaryOp Add
- Out-of-scope patterns return Ok(None) for fallback
- SSOT documentation added (lines 29-46)
Tests: 5 fixtures + 10 smoke tests (5 VM + 5 LLVM EXE), all PASS
