* fix(mobile): preserve long terminal and chat pastes Agents can keep only the last ~1 KiB read of unframed input (#13332). Frame long single-line chat messages like multi-line ones, and frame Live input appends over 1 KiB (an OS paste) with the terminal's paste rule, including held text flushed before a terminal click. Co-authored-by: Carlos Baraza Haro <carlos.baraza@ieee.org> * fix(mobile): end the live input session after a framed paste Agents such as Codex collapse a framed paste into one token, so later per-character erases from the field mirror desynced the line. A long append to a terminal in bracketed paste mode now commits the whole field in one frame and clears the field, recording it like other session ends so a late native echo cannot send the paste twice; without that mode the paste stays unframed and editable. Chat sends measure the sanitized bytes when deciding to frame. --------- Co-authored-by: Carlos Baraza Haro <carlos.baraza@ieee.org> Co-authored-by: Kelvin Amoaba <97001695+AmoabaKelvin@users.noreply.github.com>
