multi-tenant Phase 1: user registry + per-user memory

Browse Source 
- CDK: add agent-claw-users DynamoDB table (actor_id PK, RETAIN policy)
- CDK: grant agent-runner read/write on users table; add USERS_TABLE_NAME env
- CDK: fix cdk.json app field (was object, must be command string)
- CDK: add UsersTableName output
- agent-runner: get_or_create_user() auto-registers users on first contact
  (stores display_name, telegram_username, created_at, allowed)
- agent-runner: pass user_profile in AgentCore payload
- prompt_builder: split base prompt (cached) from per-user context (injected per-call)
  removes USER.md/MEMORY.md from shared load; user name/username injected dynamically
- main.py: extract user_profile from payload, build user_context string for prompt
