Summary

  • clear a wide character left in the final column when row resizing truncates its continuation cell
  • add a public-API regression test for narrowing a terminal and overwriting the stranded cell

Fixes #1267.

Testing

  • cargo test -p construct-daemon session::pty::
  • cargo build --workspace --all-targets --locked

Review artifacts

No recording: this fixes an internal panic without changing intended TUI rendering.
