daily-ambient-context-optimizer: add gh-aw CLI preflight and noop fallback path

[Copilot]

The daily ambient-context optimizer could produce empty output when MCP CLI commands were unavailable. This change makes CLI readiness explicit and adds a deterministic fallback path so runs fail clearly instead of silently yielding empty reports.

• Workflow runtime readiness

  • Adds an explicit setup step to install/upgrade github/gh-aw as a gh extension before analysis begins.
  • Verifies CLI availability with gh aw --version during setup.

• Prompt-level preflight contract

  • Adds an MCP CLI Preflight section requiring:
    • gh --version
    • gh aw --version
    • gh aw logs --help
  • Instructs the agent to stop early and emit noop with the failed command when preflight fails.

• Safe-output wiring for failure handling

  • Extends safe-outputs.noop config with explicit limits/behavior to support the preflight failure path (max, report-as-issue).
