Spread scheduled agentic workflows across 24 hours and add 6-hour schedules to smoke tests

[Copilot]

Overview

This PR redistributes the scheduled agentic workflows to run evenly throughout the day and adds automated 6-hour schedules to all smoke test workflows for continuous monitoring.

Problem

Previously, workflows were heavily clustered at specific times during the day:

• 9am UTC: 3-4 workflows running concurrently
• 10am UTC: 3-4 workflows running concurrently
• 11am UTC: 1 workflow
• Other hours: Minimal activity
• Smoke tests: No automated schedules (manual trigger only)

This clustering led to:

• Peak resource contention during morning hours
• Underutilization during other times
• No continuous monitoring of AI engines between manual test runs

Changes

Daily Workflows - Now Spread Across 24 Hours

Rescheduled 6 daily workflows to distribute load evenly (approximately every 3 hours):

• daily-doc-updater.md: 9am → 6am UTC
• go-logger.md: 9am → 12pm UTC
• cli-version-checker.md: 10am → 3pm UTC
• copilot-agent-analysis.md: 10am → 6pm UTC
• duplicate-code-detector.md: 11am → 9pm UTC
• unbloat-docs.md: 10am → 10pm UTC

Unchanged (already well-distributed):

• audit-workflows.md: 12am UTC
• lockfile-stats.md: 3am UTC
• daily-news.md: 9am UTC (weekdays only)

Weekly Workflows - Distributed Across Weekend

Spread weekly workflows across Sunday and Monday to avoid clustering:

• artifacts-summary.md: Sunday 9am → Sunday 6am UTC
• github-mcp-tools-report.md: Sunday 9am → Sunday 12pm UTC
• example-workflow-analyzer.md: Monday 9am UTC (unchanged)
• weekly-issue-summary.md: Monday 9am → Monday 3pm UTC
• mcp-inspector.md: Monday 10am → Monday 6pm UTC

Smoke Tests - Every 6 Hours

Added automated schedules to all 5 smoke test workflows:

schedule:
  - cron: "0 0,6,12,18 * * *"  # Every 6 hours

Now running 4 times daily at: 12am, 6am, 12pm, 6pm UTC

• smoke-claude.md
• smoke-codex.md
• smoke-copilot.md
• smoke-genaiscript.md
• smoke-opencode.md

Benefits

✅ Better load distribution: Maximum of 1 daily workflow per hour (down from 4)
✅ Continuous monitoring: Smoke tests run every 6 hours automatically
✅ Faster issue detection: 4x daily engine validation catches problems earlier
✅ Improved resource utilization: Workflows spread across all hours
✅ Reduced peak contention: No more morning workflow clusters

Verification

• ✅ All 42 workflows compiled successfully with 0 errors
• ✅ All unit tests pass
• ✅ Lock files (.lock.yml) regenerated with new schedules
• ✅ YAML syntax validated

Original prompt

• Review the scheduled agentic workflows and spread them the entire day.
• Schedule the smoke workflows every 6h
