A small persistent service (bot/app.py) that reuses the ci-ai modules
(llm.py->Jetson, gitea_api.py, ai_review prompt). Handles issue_comment
@ci-ai mentions as threaded chat and pull_request events as idempotent
reviews — answering in seconds via webhook, with NO runner/clone/hairpin.
Runs on the Pi next to Gitea (internal http://gitea:3000 API).
