[cli-tools-test] logs: empty message field when no results found (future/old dates return no guidance)

[github-actions]

When the logs tool returns zero results due to a query with a future date or a very old date beyond retention, the message field in the response is an empty string. This provides no guidance about why no results were found.

In contrast, querying a non-existent workflow name correctly returns a helpful message: "workflow 'x' not found. Use the 'status' tool..."

Steps to Reproduce

1. Run: agenticworkflows logs --start_date "2030-01-01" --count 3 --max_tokens 3000
2. Read the cached JSON at the returned file_path
3. Check the message field

Expected Behavior

The message field should explain why no results were found, e.g.:

• Future date: "No runs found. The start_date '2030-01-01' is in the future."
• Old date: "No runs found. Data may not be available beyond the 90-day retention period."

Actual Behavior

{"summary": {"total_runs": 0}, "runs": [], "message": ""}

The message field is an empty string — zero guidance.

Environment

• Repository: github/gh-aw
• Run ID: 28221459539 (daily-cli-tools-tester, 2026-06-26)

Impact

• Severity: Medium
• Frequency: Always (reproducible with any future date or date beyond retention)
• Workaround: None — user receives no feedback
