From github.com/darlingm/tmux, branch pr5516-regression-fixes. Adds 9 regression tests covering gaps found in the redraw-damage-rectangles branch: screen-write full/region redraw fallback, same-session window switches, wide-character clipping at damage edges, pane prompts and status lines surviving damage, floating-pane status format refresh, and multi-client damage delivery. redraw-multiclient.sh is adapted here to use ASCII pane borders (pane-border-lines simple) instead of darlingm's original UTF-8 borders: the original reliably "failed" under this test's nested tmux-in-tmux harness (relaying through an outer tmux client) due to that harness mis-rendering a cell that held a multi-byte UTF-8 border character being overwritten by later plain content - confirmed to be a nested-relay artifact, not a real bug, by replaying the identical drag sequence against a real terminal (xterm), where it never reproduces. ASCII borders avoid the artifact; the test still reliably catches the real "damage consumed by only one client" bug it targets (verified by reintroducing that bug and confirming the test fails). The other 8 tests are added verbatim from darlingm's branch. Four of them (popup-drag-status-line.sh, popup-drag-wide-character.sh, popup-drag-pane-prompt.sh, switch-client-redraw.sh) currently FAIL on this branch, since the source fixes they test for have not been merged yet - only the tests are being added here.
