"""Confluence Atlassian Connect webhook: lifecycle + comment-created handler.

Lifecycle (installed/uninstalled) implements the verify-before-overwrite guard;
the comment handler mirrors ``webhooks/jira.py:process_jira_issue`` with the
Phase-2 lesson baked in: the JWT-signed webhook body is only a pointer, so the
triggering comment's real author, text, and container are re-fetched server-side
via the Basic-auth service account before anything security-relevant is derived.
