docs: sync examples index references

[choucaleb602-commits]

Description

Syncs the example-script references introduced by the examples index follow-up:

• updates docs/usage/agent_loops.md so the quick matrix no longer contradicts examples/README.md
• adds a PR-template checkbox for maintaining examples/README.md when runnable scripts change
• updates the documentation-only workflow row to mention examples/README.md for runnable-script additions, renames, or removals

This PR was prepared with AI assistance under human supervision. I kept the change small and included the checks I ran below.

Type of Change (Matches Issue Templates)

• Skill Proposal: New Skill (Contains manifest.yaml, skill.py, and instructions.md)
• Bug Report Fix: Non-breaking change which fixes an execution error or framework bug
• Doc Fix: Documentation Update
• Framework Feature / RFC Updates: Core Framework Update (Changes to base_skill.py, loader.py, etc.)

Checklist (all PRs)

• My code follows the Agent Code of Conduct.
• I have run python -m flake8 . and pytest tests/ locally (or the subset relevant to this change).
  • python -m flake8 . could not run because flake8 is not installed in this local Python environment.
  • python -m pytest tests/ -q stopped during collection because optional dependency anthropic is not installed for tests/skills/office/test_pdf_form_filler.py.
  • Relevant focused check python -m pytest tests/test_cli.py -q passed.
• examples/README.md is updated if this PR adds, renames, or removes a runnable script under examples/.
  • No runnable scripts were added, renamed, or removed; the existing index was used as the source of truth.

New or updated skill
