Make all fields optional in missing_data safe output tool

[Copilot]

The missing_data safe output tool required data_type and reason fields, causing validation errors when the model couldn't provide specific details. The tool should allow the model to signal missing data without mandatory context.

Changes

Schema updates

• Removed data_type and reason from required fields in both pkg/workflow/js/safe_outputs_tools.json and actions/setup/js/safe_outputs_tools.json

Handler implementation (actions/setup/js/missing_data.cjs)

• Removed field validation logic
• All fields now default to null when not provided
• Conditional logging based on field presence

Test coverage (actions/setup/js/missing_data.test.cjs)

• Added tests for empty messages, partial fields, and optional combinations
• Removed tests expecting validation failures

Example

Previously would fail:

// ❌ Error: missing or empty 'data_type', 'reason'
{ type: "missing_data" }

Now succeeds with all scenarios:

// ✅ All valid
{ type: "missing_data" }
{ type: "missing_data", data_type: "credentials" }
{ type: "missing_data", reason: "Need API key" }
{ type: "missing_data", data_type: "credentials", reason: "Need API key" }

Original prompt

All fields in the "missing_data" safe output tool should be optional. The model can just tell us it's missing something.

❌ safeoutputs-missing_data
