Display examples showing 'cd $TARGET_PATH' and 'cd $WORKSPACE_PATH/repo1'
were unquoted, causing path splitting when project paths contain spaces
(e.g. Windows paths like C:\Users\First Last\...).
Quote all path variable references in user-facing guidance blocks so
the examples shown to users are safe to copy-paste directly.
The actual bash execution blocks (git worktree add, rm -rf, etc.) were
already correctly quoted — this fixes only the display examples.
Fixes#2088
