Styling

• Text show rules now have tracebacks that include the matched text
• Fixed a crash with text show rules that match on multi-character symbols

Scripting

• Extended hint when built-in definitions are shadowed to set and show rules
• Added hint when trying to spread one or multiple dictionaries into an array
• Improved diagnostics for invalid method calls
• Improved hint for unknown variables in math that are available in std
