Note

Introduces cross-platform file logging that tees printf output to a log file when running with --openframe-mode, and updates CI to build this feature branch.

• Core / Logging:
  • Add meshcore/openframe_file_logger.h implementing cross-platform file logging that duplicates printf to console and file, with daemon/service detection and thread-safety.
  • Wire logging into meshcore/agentcore.c:
    • Include openframe_file_logger.h.
    • On --openframe-mode, set fixed log directory (C:\\ProgramData\\OpenFrame\\meshcentral-agent on Windows, /var/log/openframe/meshcentral-agent on POSIX) and call enable_file_logging(logDir, "meshagent").
• CI:
  • Update .github/workflows/build.yml to trigger on feature/improve-logging in addition to master.
• Meta:
  • Bump commit metadata in microscript/ILibDuktape_Commit.h.
