Hz_ 1b77e3ebcd fix(go-agent): preserve canvas system state across turns (#17010) ...

## Summary

- Preserve request-scoped system variables such as files and user IDs
during Canvas execution.
- Persist conversation history, turn counts, and tool memory in the
session DSL across turns.
- Parse agent uploads into `sys.files` and align system variable
rendering with Python.

## Testing

- `bash build.sh --test ./internal/agent/...`
- `bash build.sh --test ./internal/service/...`
