### Summary
- TavilySearch now stores api_key from component params and injects it
into tool calls when runtime inputs omit it.
- TavilyExtract and BGPT now follow the same stored api_key behavior.
- Canvas decoding now recovers api_key from graph.nodes[].data.form when
components[].obj.params.api_key is empty, matching frontend payload
behavior without changing frontend data.
- Added regression tests for graph form key recovery and stored key
injection / caller key precedence.
Tests: build.sh --test ./internal/agent/component ./internal/service —
all pass.

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).
