Two string-utility edge-case fixes: normalizePath leading-backslash & formatTitle empty-segment spacing (PRs ready, pending Discussion)

Summary I opened two small, self-contained bug fixes in Directus's string utilities. They were closed with a note that a PR needs a prior accepted Discussion, so I'm opening this to get a maintainer greenlight before resubmitting. Both are minimal, fully tested, and ship a changeset.
