feat(tools): add persistent shell mode to local and SSH backends

Browse source 
Cherry-picked from PR #1067 by alt-glitch.
Adds PersistentShellMixin with file-based IPC protocol for long-lived
bash shells. LocalEnvironment and SSHEnvironment gain persistent=True
option. Controlled via TERMINAL_LOCAL_PERSISTENT / TERMINAL_SSH_PERSISTENT
env vars. Fixes latent stderr pipe buffer deadlock.
