feat(ai): add execute_workflow and get_workflow_execution_status to data_workflows_tool

[bertenator]

JIRA: https://webflow.atlassian.net/browse/DEVPL-3947

Summary

Extends data_workflows_tool with two new actions, completing the execute workflow capability:

• execute_workflow — POST /v2/sites/:site_id/workflows/:workflow_id/execute — triggers an AI workflow; returns { executionId, workflowId }
• get_workflow_execution_status — GET /v2/sites/:site_id/workflows/executions/:execution_id — polls an execution; returns { executionId, status, startedAt, stoppedAt, isFinished }
• Also refactors the per-action fetch calls into a shared apiRequest helper, and extracts the action dispatch loop into a handleWorkflowActions helper

Depends on: webflow/webflow#101439 (the OAuth v2 routes for execute + get-status)

Agent workflow this enables

list_workflows → pick a workflow_id
execute_workflow → get execution_id
get_workflow_execution_status (poll) → wait for isFinished: true

Test plan

• Set WEBFLOW_TOKEN for a site with AI_WORKFLOWS flag enabled
• Call data_workflows_tool with execute_workflow: { site_id, workflow_id } → verify { executionId, workflowId } returned
• Call data_workflows_tool with get_workflow_execution_status: { site_id, execution_id } → verify { status, isFinished } returned
• Call with an inactive workflow → verify 400 surfaced via formatErrorResponse
• All three actions (list_workflows, execute_workflow, get_workflow_execution_status) work in the same actions array call

@bertenator you may need to rebase it

[viratatwebflow]

remove the tool entry point from here

[viratatwebflow]

can we move to its own helper function?

[4vanger]

nit since it is always used only in this way

Suggested change

	return response.json();
	return textContent(response.json());

Hey @viratatwebflow — addressing the review feedback here:

1. "remove the tool entry point from here" (mcp.ts) — removed registerWorkflowsTools from registerTools(). It's already registered via the dedicated registerWorkflowTools() export so it was a duplicate.

2. "can we move to its own helper function?" (workflows.ts) — extracted the action dispatch loop into handleWorkflowActions(). The tool handler is now just a 4-line try/catch.

3. Rebase — branch is up to date with sai, no rebase needed.

4. Dependency — webflow/webflow#101439 is now in production, so this is unblocked and ready to merge.
