Report missing_data safe output calls in agent failure issues

[Copilot]

Agent workflows calling missing_data safe output had this diagnostic information silently dropped in conclusion job failure reports, making debugging failures unnecessarily difficult.

Changes

Core logic (handle_agent_failure.cjs):

• loadMissingDataMessages() - extracts missing_data from agent output file
• buildMissingDataContext() - formats using existing formatMissingData() helper
• Added missing_data_context to both issue and comment template contexts

Templates:

• agent_failure_issue.md and agent_failure_comment.md now include {missing_data_context} placeholder

Test coverage:

• Added test validating missing_data appears in failure issues with all fields (data_type, reason, context, alternatives)

Output

Failure issues now include:

⚠️ Missing Data Reported: The agent reported missing data during execution.

Missing Data:
- **GitHub API token**: Required for accessing private repositories
  - *Context*: Workflow needs to read issues from private repo
  - *Alternatives*: Use a personal access token or GitHub App

Original prompt

A call to missing data safe outout should be reported in the agent failure issue/comment in the conclusion job

The cleanup logic uses fs.rmdirSync() which only removes empty directories. Since the directory should only contain agent_output.json which is deleted on line 1278, this should work. However, consider using fs.rmSync(tempDir, { recursive: true }) (available in Node.js 14.14.0+) for more robust cleanup that doesn't rely on the directory being empty.

Suggested change

	fs.rmdirSync(tempDir);
	fs.rmSync(tempDir, { recursive: true, force: true });
