feat(layout): implement deterministic 2xK grid engine with single decision table

- Change N=1->2 split policy from down to right to establish 2 full-height columns
- Share single decision table across GUI and headless modes
- Add _full_height_pane guard to prevent half-height column splits
- Quadruple-wire default max_columns=2 and max_rows=2 across layout.py, lib.sh, and .mam.env.example
- Update unit and integration tests to enforce deterministic 2x2 grid trajectory
