Terminal left in raw mode on exit (Alacritty, Ubuntu 24.04, zsh, v1.17.9)

Summary
On exit (both Ctrl+C and Ctrl+D), opencode returns to the shell but the TTY stays in raw mode — no echo, can't type. A second Ctrl+C resets the line discipline and restores input. stty sane also fixes it.

Environment

opencode 1.17.9
Ubuntu 24.04.4 LTS (kernel 6.17.0-1025-oem, x86_64)
Alacritty (Wayland session)
zsh
TERM=xterm-256color, COLORTERM=truecolor
No tmux, no SSH

Repro

Launch opencode
Exit via Ctrl+C or Ctrl+D
Shell is unresponsive (no echo) until a 2nd Ctrl+C or stty sane

Expected
termios restored, cursor shown, alt-screen exited on quit.

This issue might be a duplicate of existing issues. Please check:

Terminal raw mode not restored after abnormal exit — input broken, Ctrl-like behavior #30920: Terminal raw mode not restored after abnormal exit — same symptom of TTY left in raw mode requiring stty sane/second Ctrl+C to recover
TUI: incomplete terminal teardown on exit — mouse tracking, alt-screen, bracketed paste left enabled #32336: TUI incomplete terminal teardown on exit — same root cause of termios/terminal state not fully restored on exit (mouse tracking, alt-screen, bracketed paste left enabled)

Duplicate of #17081 (POSIX raw mode not restored on exit). Consolidating there.
