Phase 0: CDK stack + Lambdas + AgentCore Runtime 1 scaffold

- CDK TypeScript stack (AgentClawStack):
  - S3 workspace bucket with BucketDeployment seed
  - DynamoDB session-store (actor_id → session_id, TTL)
  - SQS FIFO message queue (serialized per actor)
  - Lambda: tg-ingest (webhook validation, typing action, SQS enqueue)
  - Lambda: agent-runner (SQS → InvokeAgentRuntime, session management)
  - API Gateway HTTP: POST /telegram → tg-ingest
  - AgentCore Runtime 1 IAM execution role
  - CDK outputs: WebhookUrl, WorkspaceBucketName, Runtime1RoleArn

- Runtime 1 (Python + Strands + BedrockAgentCoreApp):
  - main.py: entrypoint, Strands agent, tool wiring
  - channels/: ChannelAdapter Protocol + TelegramAdapter (decoupled)
  - tools/: web_search (Brave), web_fetch, read/write_workspace_file, send_message
  - prompt_builder.py: loads SOUL.md/AGENTS.md/USER.md from S3 (cached)

- Lambdas:
  - tg-ingest: validate X-Telegram-Bot-Api-Secret-Token, send typing, enqueue FIFO
  - agent-runner: session lookup/create in DDB, bundle batched messages, InvokeAgentRuntime

- workspace/: seed files (SOUL.md, AGENTS.md, USER.md, IDENTITY.md, HEARTBEAT.md)

NOTE: AgentCore Runtime 1 creation via CfnResource deferred — deploy CDK first,
create runtime manually with the output Role ARN, then redeploy with runtime1Arn context param.
