Update the full-scrollback replay invariant (per-session full=1 Set plus
the scroll-to-top re-pull), add a new invariants section covering the two
strip flavors and the wheel/touch forwarding rules, sync the CLAUDE.md
Key Patterns bullets, and commit the fix plan with a status header
describing what shipped and where it deliberately diverged (narrow strip
plus re-pull instead of tmux mouse on; viewport-at-bottom gate dropped).
