fix(plan-mode): compared canonical local urls for scan membership

The scan-membership test used a raw string includes, so a resumed single-slash local:/ state path failed to match the scanner's local:// entry and wrongly gained precedence over a newer draft. Normalize both sides via normalizeLocalScheme before comparing.

Fixes #6569
