Fix Claude API incompatibility in update_project tool schema

[Copilot]

Campaign workflows failed with Claude Sonnet 4.5 due to oneOf at the top level of the update_project tool's input schema. Anthropic's API does not support oneOf, allOf, or anyOf at the schema root.

Changes

Flattened tool schema structure

• Removed top-level oneOf discriminated union
• Made project the only required field
• Documented three usage modes in tool description:
  1. Add/update project item (requires content_type)
  2. Create project fields (requires operation='create_fields' + field_definitions)
  3. Create project view (requires operation='create_view' + view)

Before:

{
  "inputSchema": {
    "type": "object",
    "oneOf": [
      {"required": ["project", "operation", "field_definitions"]},
      {"required": ["project", "operation", "view"]},
      {"required": ["project", "content_type"]}
    ],
    "properties": {...}
  }
}

After:

{
  "inputSchema": {
    "type": "object",
    "required": ["project"],
    "properties": {
      "operation": {
        "description": "Optional operation mode. Use create_fields to create required campaign fields up-front, or create_view to add a project view. When omitted, the tool adds/updates project items."
      },
      "content_type": {
        "description": "Type of item to add to the project. Required when operation is not specified."
      }
      // ... other fields with clarified descriptions
    }
  }
}

Impact

• Campaign workflows using Claude Sonnet 4.5 can now execute successfully
• No breaking changes - existing tool calls remain compatible
• Applied to both actions/setup/js/safe_outputs_tools.json and pkg/workflow/js/safe_outputs_tools.json
