feat(environment): system_launch, preference whitelist and operator prompts on COM; declared refusals headlessly

Browse Source 
user_pick_point / user_select answer {cancelled: true} on ESC (DISP_E_EXCEPTION)
and {timed_out: true} past COM_CALL_TIMEOUT; preferences_set refuses read-only,
unknown and out-of-range keys before any ActiveX call.

The read-only key is Files.PrinterStyleSheetPath, not the spec's
PrintStyleSheetPath: IAcadPreferencesFiles has no member of that name
(measured live on AutoCAD 2026 / R25.1), and a misspelt key would make
preferences_get() raise on every live call.
