feat(commands): add CLOSE, HIDE, VISUALSTYLES, QUICKCALC, HYPERLINK, XOPEN

Six more standard commands by reusing existing infrastructure: - CLOSE: close the active tab (Message::TabClose) - HIDE / VISUALSTYLES: per-viewport render mode (Message::SetRenderMode) - QUICKCALC / QC: alias the CAL arithmetic evaluator - HYPERLINK <url>: attach a hyperlink via the PE_URL XData record - XOPEN: open a selected xref's source file (Message::OpenRecent) COMMANDS.md updated to 214 done / 15 partial / 33 missing of 262.
