I have a related issue on 0.21, in short the termal does not work if I open it on a large monitor
[Terminal] Wide terminal pane fails to open when calculated cols exceed schema cap
T3 Code terminal fails to open in a wide window because the frontend sends
cols: 499, while the terminal RPC schema rejects values greater than 400.Error:
[terminal] Expected a value less than or equal to 400, got 499
at ["cols"]
Expected:
The terminal should open normally in wide windows, either by supporting the
calculated width or clamping dimensions before calling terminal.open/resize.
Actual:
The terminal displays a validation error and does not start.
Affected code:
Workaround:
Narrow the T3 Code window/pane or zoom in until the terminal calculates <= 400 cols.

Terminal dimension schemas now accept ultrawide values up to 1000 columns and include coverage for 423-column terminals, fixing the old 400-column failure.
