- Dynamic tool schemas when multi-container enabled (optional container_tag param)
- Whitelist validation for custom container tags in tool calls

- Defer container_tag sanitization to initialize() (after template resolution)

- Update README with multi-container docs, search_mode, identity template,
support links (Discord, email)
