chore(main): release agent-engine 1.0.0

[github-actions]

🤖 I have created a release beep boop

1.0.0 (2026-08-31)

⚠ BREAKING CHANGES

• adr: GET /conversations response shape changed from flat list [ConversationSummary] to paginated envelope { items: [ConversationSummary], next_cursor: str | null }
• manager: X-Agent-Chat-User and the widget's user attribute are removed. Every conversation route now requires a verified token; requests without one are 401. Conversations already stored under unverified ids become unreachable rather than exposed.
