Update member role

curl "https://herculeradar.com/api/v1/members/:id" \
  --request PATCH \
  --header "Authorization: Bearer hr_live_…" \
  --header "Content-Type: application/json" \
  --header "Idempotency-Key: $(uuidgen)" \
  --data '{"role":"editor"}'

Tool name update_project_member. It takes the same input and returns the same { data, meta } envelope as REST, because both call the same function.

Change a member between viewer and editor.

    "role": {
      "type": "string",

  "data": {
    "user_id": "uuid",
    "role": "editor"
  },

    "capability": "update_project_member",

  }
}

Requires the projects:write scope. A credential without it gets 403 FORBIDDEN. Resources in projects the credential cannot reach answer 404 NOT_FOUND rather than 403, so ids cannot be probed across tenants.

Send an Idempotency-Key header. A completed response is replayed for 24 hours, so a retry after a timeout cannot create a duplicate.
