refactor(ast): rename value types to Number/Decimal/Text/Boolean

Renamed AST value types for v0.3 naming convention:
- Value::Int -> Value::Number
- Value::Float -> Value::Decimal
- Value::String -> Value::Text
- Value::Bool -> Value::Boolean
- Expr::IntLit -> Expr::NumberLit
- Expr::FloatLit -> Expr::DecimalLit
- Expr::StringLit -> Expr::TextLit
- Expr::BoolLit -> Expr::BooleanLit

Updated all references across parser, resolver, validator, LSP,
query engine, tests, and editor.
