0.6.9: The Resident Host Restarts Again

• Unit Working Directory: 0.6.7 quoted WorkingDirectory=, but systemd parses path settings verbatim, so the quotes became part of the path and every reload answered path is not absolute and bad unit file setting. /telegram-host restart rewrites that unit before restarting, so it broke the installed host it was asked to repair. Path settings now render literally, % is escaped as %% in every expanded value, and systemd-analyze verify accepts the rendered unit.
• Host Action Completions: /telegram-host registered no argument completions, so its actions were invisible at the prompt. It now completes install, uninstall, restart, status, and attach with descriptions, then offers --dry-run for the three actions that change the system.
