feat: add document tool executor with config, registration, and approved flag in ToolContext

- Create document executor config (approvalRequiredActions, defaultType, maxContentLength, listPageSize)
- Implement document executor with create/read/update/delete/list actions
- Register document executor in TOOL_TYPE_REGISTRY
- Extend ToolContext with approved?: boolean field
- Update executeAgentTool signature to accept approved parameter
- Pass approved flag from chat-engine to executeAgentTool
- Remove stale guess-who references (executor never existed)
