## Summary
- Add the GitHub Canvas component with tool registration and reference
propagation.
- Align the Invoke component with the Python contract for node config,
input form, response output, and timing fields.
- GitHub search and HTTP Invoke now work correctly in the Go Canvas
runtime.
## Tests
- `bash build.sh --test ./internal/agent/tool/...`
- `bash build.sh --test ./internal/agent/component/...`
Note: the untracked go_ragflow_cli file is not part of the PR changes.

Replaces the Python agent canvas runtime with a Go implementation that
runs inside `cmd/server_main`.
The canvas compiles into an eino Workflow that pauses on wait-for-user
via native Interrupt/Resume (no sentinel flag) and resumes from a
Redis-backed CheckPointStore.
All 21 Python agent components and ~35 tools are ported with functional
parity.
Sandbox providers now read their JSON config from the admin-panel
system_settings table with env fallback.
234 files / +35,413 / -6,111. All Go files are gofmt-clean (CI gate
added); drops the v2 DSL E2E step and the gap-analysis plan (both
redundant after the port ships).
