nyash-codex 41c50e4780 feat(joinir): Phase 172-3 ExitMeta unified return from Pattern2 lowerer ...

Implement loop exit contract boxification for JoinIR Pattern2:

- lower_loop_with_break_minimal now returns (JoinModule, ExitMeta)
- ExitMeta contains k_exit parameter ValueId for carrier variables
- Pattern2 caller builds exit_bindings from ExitMeta
- merge/mod.rs adds exit_bindings join_exit_values to used_values for remap
- reconnect_boundary uses remapped exit values for variable_map updates

This completes Phases 172-3 through 172-5 of the Loop Exit Contract
boxification plan, enabling proper loop variable propagation after exit.

Test: joinir_min_loop.hako passes (RC: 0)
