- Remove outdated CLAUDE.md with obsolete architecture references
- Create comprehensive AGENTS.md covering:
  - Backend: Go, gRPC, Connect RPC, store layer, migrations
  - Frontend: React, React Query, Context API, state management
  - Development commands, workflows, and testing patterns
  - Code conventions, configuration, CI/CD, and security notes

Replace dynamic hook mapping with useMemoComments hook to fetch all comments
via listMemoComments API, ensuring consistent hook order across renders and
fixing page load failure after comment creation.

The translation files ca.json and gl.json existed but weren't registered in the locales array, preventing users from selecting these languages.
