phase-20.45: Logical(AND) PRIMARY fix

Browse Source 
- lower_return_logical_box.hako: emit MIR v0 as JSON string (functions[]/main/blocks.id)
- runner_min: adopt lower.logical before binop/int
- lower_return_bool_box.hako: restrict to Return(expr=Bool) to avoid logical bleed
- add canaries: PRIMARY AND-only; update OR canary; all phase2044 quick PASS
