Debugging and more

Added

•  "Upscale small text" toggle on OCR nodes (faster native-size OCR when off)
•  Declared variables listed in canvas right-click menu (drops a Get pill)
• Multiline text initial values for String variables
• Parameterized group/custom nodes (typed input/output ports, per-call args)
• Group variables now private/scoped per call
• Breakpoints & pause/step debugging
• Settings tab with rebindable global debugger keys
• Error output ports + "On fail" setting on Click Image, Click Text, Wait Pixel
• Live run spotlight (executing node glows green)
• Live variable watch in Variables panel
• String Op node (Replace, Regex, Split, Substring, Trim, Case, etc.)
• Variables reset to initial values on every loop pass

Fixed

• Dropdown lists now scroll with the mouse wheel
• Message Box "Message" input accepts text (was mistyped as Number)
