Pull request overview

Updates the reusable change-detection workflow so PR CI can be skipped when only design notes are modified.

Changes:

• Add eng/design-notes/** to the default file patterns used to determine “only docs/notes changed”.

[Copilot]

eng/design-notes/** matches any file type under that directory. That could unintentionally mark a PR as “docs-only” and skip CI even if non-doc artifacts (e.g., scripts, binaries, generated outputs) are added there later. Narrow the default patterns to markdown files only (e.g., eng/design-notes/**/*.md / eng/design-notes/*.md) to keep the skip behavior scoped to design notes content.

Suggested change

	eng/design-notes/**
	eng/design-notes/**/*.md
	eng/design-notes/*.md

Should we also add specs/ to the list?
