[instructions] Sync instruction files with release v0.81.6

[github-actions]

Summary

Documentation-only fixes to instruction files, synced with release v0.81.6. Corrects a stale action reference and two broken cross-reference links.

Changes

File	Change
.github/aw/debug-agentic-workflow.md	Fixed action reference: actions/setup-cli to github/gh-aw/actions/setup-cli
.github/aw/runbooks/workflow-health.md	Same action reference fix; replaced broken link to cli-commands.md
.github/aw/token-optimization.md	Fixed broken cross-reference to syntax-agentic.md#agentic-workflow-specific-fields

Details

The setup-cli action was incorrectly referenced by the short form actions/setup-cli in two instruction files. The correct fully-qualified reference is github/gh-aw/actions/setup-cli.

Cross-reference fixes:

• workflow-health.md: Replaced stale anchor github-agentic-workflows.md#logs-and-metrics with direct link to cli-commands.md.
• token-optimization.md: Updated syntax.md#observability to syntax-agentic.md#agentic-workflow-specific-fields.

Impact

• Code: none
• Behaviour: none
• Documentation: fixes stale/broken links and an incorrect action reference in agent-facing instruction files

👋 Thanks for the tidy accuracy pass — fixing a wrong action org prefix and two dead anchors in the instruction files is exactly the kind of hygiene that keeps agents from following stale guidance.

One thing worth considering:

• No test coverage — the diff is purely in .md files, so traditional unit tests don't apply. That said, an automated anchor-validation step (e.g. a script or CI job that crawls .github/aw/**/*.md for broken #fragment links) would catch regressions like these before they ship and make future janitor passes smaller.

If you'd like to add that guard, here's a prompt you can hand off to an agent:

Add a CI check (or Makefile target) that validates all intra-doc anchor links in `.github/aw/**/*.md`.
For each `[text](file.md#fragment)` reference found in those files:
1. Confirm the target file exists.
2. Confirm a heading whose slugified form matches the fragment exists in that file.
Report any broken references as errors and exit non-zero so the check can be wired into CI.
