chore(coding-plans): drop stray .next/dev/dev/types tsconfig include

This duplicated glob with a doubled dev/dev segment was auto-written into
tsconfig.json by the Next dev server and committed by mistake. It points
at a nonexistent directory and duplicates the existing .next/dev/types
entry, so removing it restores tsconfig to match main.
