Fix script confirmer

[bennert]

Summary
This PR contains two related fixes:

• Fix script parser confirmer interaction handling.
• Allow unquoted INFO(...) text to be parsed as STRING in Definition lexer conditions.

Why

• The script confirmer flow needed more reliable parser interaction handling.
• Some Definition files can contain condition text in the form : INFO(...); this should parse the same way as the quoted form : "INFO(...)".

What changed
Script parser confirmer handling

• Updated script parser logic in: script_parser.y
• Includes related generated parser updates in Source/Libraries/Scripting.

Definition lexer support for unquoted INFO(...)

• Added lexer support to tokenize INFO(...) as STRING in:

  • definition_lex.l

  • definition_lex.l

  • definition_lex.cpp

Validation
Built the Definition parser/library successfully for the Source tree:

• Definition.vcxproj
