DBabel v1.5.0

• Added DBabel Review Workbench for explicit human-in-the-loop bilingual review.
• Added .dbreview Review Sessions, review schemas, evidence/issues/decision
  contracts, and local/portable review surfaces.
• Added DOCX native export with Export Gate, original-file hashing, anchor checks,
  non-destructive output, and round-trip verification.
• Bound Portable Review decision exports to their originating Review Session and
  made malformed or cross-session imports fail closed.
• Prevented bilingual DOCX extraction from silently dropping unmatched paragraphs
  when source/target paragraph counts differ.
• Added an Agent-to-Workbench handoff contract so suggestions and findings never
  become fabricated human approval.
• Added explicit review-only versus native-export mode feedback.
• Added explicit auditable DOCX alignment maps for ALIGNED, SPLIT, MERGED,
  UNALIGNED, and AMBIGUOUS relationships, with complete paragraph coverage
  checks and fail-closed native write-back for non-ALIGNED units.
• Strengthened DOCX anchors with Word w14:paraId identity and fail-closed
  behavior when a previously anchored paragraph ID disappears.
• Added DOCX structure guards for field codes and tracked revisions while
  regression-testing paragraph extraction inside tables, hyperlinks, and
  content controls.
• Made desktop bulk review updates transactional, preserved reviewer notes,
  prevented hidden selections from leaking across filters/pages, and retained
  safe local bulk behavior in Portable Review.
• Removed or explicitly disabled remaining inactive Workbench controls and
  completed Portable Review copy/theme compatibility hardening.
