Fixes
- brindle no longer leaves tmux sessions behind. When a task's workspace is removed after merging, brindle now closes that task's own tmux session. Your own sessions, and any you have open, are never touched.
- No more leftover Codex background processes. The
codex app-serverprocesses brindle starts while setting up its Codex hook now always stop, even when that step fails or times out.
