[BUG] Choosing fullscreen renderer offered on tui after starting claude first removes bypassPermissions mode arguments

What's Wrong?

When I run the "claude" command first and I am asked whether I want to try the "fullscreen renderer", if I choose "yes", my original cli arguments are reset. Some arguments are kept like "--allow-dangerously-skip-permissions", but others are removed like "--dangerously-skip-permissions" or "--permissionMode bypassPermissions".

When I chose "no" and later manually run "/tui fullscreen", arguments are changed. "--dangerously-skip-permissions" replaced with "--allow-dangerously-skip-permissions --permissionMode bypassPermissions" so it still works as expected, but not when I choose it on the TUI immediately.

What Should Happen?

Permissions should still by bypassed even if with different arguments so claude could be used more freely in an isolated environment like Docker Sandboxes.

`ps auxf` output after choosing "fullscreen renderer" during the initialization of the sandbox on the tui:


USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
agent        443  0.0  0.0   5120  3952 pts/1    Ss   15:34   0:00 bash

Steps to Reproduce

1. Have a clean environment like a container or a new machine, or remove /.claude and settings files like ~/.claude.json
2. Run claude --dangerously-skip-permissions or even claude --allow-dangerously-skip-permissions --permissions bypassPermissions
3. Do the initialization (select a color profile, authenticate, acccept security notes, trust the folder, accept that claude code is running in "Bypass Permissions mode") until the question about "Fullscreen renderer".
4. Choose "Yes, try it"
5. Check the output of ps auxf ooking for the claude command and confirm parameters were changed.
6. Ask claude to create a file and confirm it asks back for permission.
