Why smartlead_delete_lead_from_campaign needs a policy

This qualifies as Destructive with high severity given the blast radius of removing leads from active campaigns at scale.

From the tool's definition "Remove a lead from a campaign" — the word 'remove' combined with 'delete' in the tool name indicates an irreversible deletion of a lead's association with a campaign.

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "smartlead_delete_lead_from_campaign"
  ]
}
