v0.6.1

v0.6.1 Release Notes

This patch release hardens Windows LibreOffice smoke coverage and runtime
resolution for the libreoffice extraction path.

Highlights

• Added a dedicated Windows GitHub Actions LibreOffice smoke job:
  • runs on windows-2025
  • installs libreoffice-fresh
  • discovers EXSTRUCT_LIBREOFFICE_PATH and bundled LibreOffice Python
  • runs tests/core/test_libreoffice_smoke.py -m libreoffice with
    RUN_LIBREOFFICE_SMOKE=1
• Improved Windows runtime discovery:
  • soffice.com is now preferred over soffice.exe when available
  • bundled LibreOffice Python detection now covers python-core-* layouts
• Hardened LibreOffice bridge subprocess startup on Windows:
  • bridge probe, handshake, and extraction now run from the runtime Python
    directory
  • the runtime directory is prepended to PATH for UNO import and DLL
    resolution
• Reduced smoke-gate false negatives:
  • slow soffice --version probes are retried with a longer timeout
  • if version probing still times out, the smoke gate falls back to a
    short-lived LibreOffice session probe before marking the runtime
    unavailable
• Added regression tests for Windows runtime normalization, bundled Python
  discovery, bridge subprocess environment handling, and timeout fallback.

Notes

• This is a reliability-focused patch release for Windows LibreOffice CI and
  runtime detection.
• No public API or output schema changes were introduced in this release.
