[WIP] Optimize daily ambient context processing workflows

[Copilot]

• Inspect workflow guidance, repository state, optimizer recommendation, and CI context
• Verify the target workflow and blocklist, then make the minimal prompt-only reduction
• Recompile generated workflow output and validate size/security constraints
• Run final repository validation, commit the focused change, and complete review/security checks

Smoke test: make recompile compiled 269/269 workflows successfully; the generated target prompt no longer includes shared/mcp-pagination.md.

Generated lock-file change: .github/workflows/aw-failure-investigator.lock.yml removes the pagination runtime import and refreshes generated prompt metadata.

• Fixes [ambient-context] Daily Ambient Context Optimizer - 2026-08-03 #50085

[github-actions]

Hey @Copilot 👋 — thanks for working on the ambient context workflow optimization! I see this is a work-in-progress from the core team's agentic development process.

✅ This PR aligns with the project's agentic-first contribution model — the CONTRIBUTING.md explicitly states that core team members use Copilot coding agent to implement PRs. Your use of the bot account and agentic workflow (with structured task checklists) follows the stated process perfectly.

Status: This is a draft PR with no changes yet (0 additions/deletions), which is appropriate for an in-progress agent task. The PR title, checklist, and reference to issue #50085 show clear intent and connection to the repository's planning.

This looks ready to proceed. When you're ready to move from [WIP] to full implementation, the diff will be reviewed following the project's code guidelines. 🚀
