Export to PDF could end in complete silence: the flow hands off to an async rfd save dialog, and when that future resolves to None the app mapped it straight to Task::none(). None does not only mean the user cancelled — on Linux the XDG portal SaveFile call can fail outright (rfd then tries a zenity fallback, which may not be installed) and the future still just resolves to None. rfd reports those failures only through the `log` crate, and logging is opt-in (--log / RUST_LOG), so the reporter saw exactly what #369 describes: no dialog, no error, no console output, no file. - EXPORT / EXPORTPDF now accept an optional path argument that exports straight to the file with no dialog — both the workaround for systems where the native save dialog cannot open and a headless-testable entry point. A relative path lands next to the drawing; a missing extension gets .pdf. - The dialog-None arms (PlotExportPath / PlotWindowExportPath) now push a command-line message pointing at EXPORTPDF <path> instead of doing nothing. - The success message prints the full output path, not just the file name, so users can find the PDF. Verified end to end on the real binary via --serve: LINE + CIRCLE then EXPORTPDF <path> writes a valid PDF with the expected geometry. Both new tests fail on the previous code.
