Add lead-actions-example.json — reference workflow demonstrating four optional
action patterns (HubSpot upsert, Slack notification, welcome email, audit log)
routed by profile grade from Workflow 1 output. Uses HTTP Request nodes for
Slack (no credential dependency), Set node for audit log (template buyers wire
their own sink), continueOnFail on all action nodes, and an Error Trigger +
email alert pair for runtime visibility.
