A lost stream or a failed Enter write returned without killing the
in-container gh, leaving it polling with a temp GH_CONFIG_DIR that would
receive the token. The output loop is now drive_login (generic over the
stream, writer and emitter, so it is unit-tested without Docker), and
its result goes through cleanup_on_error, so every ending except a token
read back runs the pkill. Neutral wording for the shared ANSI stripper's
overflow warning.

Drives `gh auth login --web` in a running project container over an
attached pty, with GH_CONFIG_DIR/GIT_CONFIG_GLOBAL in a temp dir that is
removed on exit (also on HUP/INT/TERM), emits the one-time code and
redacted output lines, and returns the token read back between markers.
Host validation reuses auth::valid_host plus a no-port check (F13); a
cancel or timeout also pkills the in-container login (N9). Reuses the
setup-token flow's AnsiStripper, push_capped_tail and Enter delay, made
pub(crate) without behaviour change.
