fix: reply in user's thread and prevent git credential hangs

Pass thread name through Add-ons response wrapper so bot replies stay
in the user's thread instead of posting top-level messages. Add
GIT_TERMINAL_PROMPT=0 to Dockerfile to prevent git from hanging on
credential prompts, which was blocking all requests under concurrency=1.
