Release notes: MANIFEST 1.1.0

The first release: migration with proof, the fix agent, the cloud runtime, the console and this help.

• Five deterministic tools: inventory, convert, restore, check and links.
• A fix agent on gemini-3.8-flash that proposes mapping rules, with two attempts per topic.
• A Cloud Run job and API that scale to zero, deployed without keys.
• A console with context-sensitive help on every screen.
• A GitHub Action that checks DITA on every pull request.
• This help, written in DITA and migrated to MyST by MANIFEST itself.
