Flux git-text in-arbore: git_sync.ps1 + teste, txt2vcx in-place, filemap pjx/dbf

- git_sync.ps1 nou: conversie recursiva bin->text in arbore (staging temp,
  incremental, orfani, RoundtripExempt, DbfList cu date, anti-dialog cfg)
- vfp_filemap.ps1: mapari .pjx->.pj2 si .dbf->.db2
- txt2vcx.ps1: CacheRoot implicit = ProjectRoot (text in-arbore) + cfg anti-dialog in staging
- test_roundtrip.ps1: parametrizat per proiect, restaurare din backup temp (nu git checkout)
- test_git_sync.ps1 nou: incremental, orfani, esec partial, protectie binar, scutire roundtrip
- CLAUDE.md: fluxul nou documentat
