chore: purge garbled Windows-path filenames; guard sync.sh against recurrence

Removed 5 tracked files whose names were mangled Windows paths (C:\ProgramData\...,
D:\claudetools\.claude\current-mode, and version-bump script fragments) — the
illegal :/\ chars were stored as Unicode Private-Use-Area substitutes (U+F03A, U+F00A).

Added purge_garbled_paths() to sync.sh: before each 'git add -A', any UNTRACKED path
containing control chars, ':', '\', or PUA U+E000-U+F8FF bytes is removed and not
staged, so this cruft never reaches Gitea again. Tracked content is never auto-deleted.
