Keep the song-centric manifest import docs mechanically clean

Constraint: Preserve the just-validated manifest import workflow while removing formatting noise from the retained docs set.
Rejected: Leave doc formatting drift after a live-validated workflow change | It accumulates avoidable friction for later edits and checks.
Confidence: high
Scope-risk: narrow
Directive: Run diff-check and docs link validation after each docs-only follow-up on the reduced docs surface.
Tested: git diff --check; /usr/local/miniconda3/bin/python scripts/check_markdown_links.py --root docs returned OK for 11 active markdown files
Not-tested: no runtime logic changes in this cleanup commit
