Root cause of second failure (120s timeout): VB InputBox has no topmost
flag and no taskbar presence, so it renders BEHIND the main window.
User never sees it, flow waits until node timeout (120000ms).
Fix:
- Dialog_InputBox now builds a WinForms form with TopMost=true,
ShowInTaskbar=true, CenterScreen, OK/Cancel buttons
- MessageBox notice adds MB_TOPMOST via options param
- Flow updated: 3 sequential InputBox nodes replaced by ONE
Dialog_GetConfigV7 form (topmost BrowserWindow via host bridge),
3 fields filled in a single window, wait_time=10min
- Flow node timeout raised to 660s to exceed the 600s PS-level wait
- Fixed latent bug: Time_WeekDay node had empty outputVar, so
the "星期几" variable never existed
Root cause: Dialog_InputBox and other blocking dialogs wait for user
input, but powershell() default timeout 30000ms kills the still-waiting
dialog process, reporting generic "Command failed" (reproduced: run
failed at 30.08s).
Fix:
- InputBox/Notice default wait 600s, adjustable via wait_time arg
- File dialogs (OpenFile/OpenFiles/SaveFile) wait up to 30min
- InputBox timeout reports dialog_timeout with clear guidance instead
of misleading command failure
