Major OXC scope info fixes:
- Fix function parameter binding kind (FormalParameter before FunctionScopedVariable)
- Fix catch parameter and rest parameter binding kinds
- Add object method scope mapping for property positions
- Handle TS type alias/enum/module bindings

AST conversion fixes:
- Include rest parameters in function param conversion
- Fix optional chain base expression conversion
- Implement ClassDeclaration reverse conversion
- Add TS declaration source text extraction
- Script source type detection via @script pragma

Test normalization improvements:
- HTML entity and unicode quote normalization
- Multi-line ternary collapsing and block comment stripping
- JSX paren wrapping normalization
