feat: add instance field support with lexer, compiler, and GC tracing Add TOKEN_FIELD token type and '_' prefix handling in lexer to distinguish field identifiers from regular names. Extend Compiler struct with fields symbol table pointer for tracking enclosing class fields. Implement field() parse function and CODE_LOAD_FIELD/CODE_STORE_FIELD bytecodes in VM. Modify ObjClass to store numFields count and ObjInstance to use flexible array member for field storage. Update GC markInstance to trace all instance fields. Add newClass signature to accept numFields parameter. Include test cases for field default null, multiple fields, object references with GC, and use-before-set ordering.

class Foo {
fix: remove default constructors and require explicit `construct new()` for all user classes The compiler no longer auto-generates a default `new()` constructor for classes. All classes must now explicitly define `construct new() {}` to be instantiable. This change removes the `createDefaultConstructor` function from the compiler, eliminates the `return_this` primitive used by Object's default initializer, and adds explicit constructors to all test and example classes. Core metaclasses (Bool, Class, Null, Num, Object, Range, Sequence) now correctly reject `new()` calls with runtime errors.

feat: rename IO.write to IO.print and add Unicode escape support in strings Rename the IO.write method to IO.print, which now prints without a trailing newline, and add a new IO.print method that appends a newline after output. Update all benchmark, example, and test files to use IO.print instead of IO.write. Additionally, implement Unicode escape sequence parsing in the compiler's string tokenizer, supporting \uXXXX and \u{...} syntax with proper UTF-8 encoding for code points up to U+10FFFF.

feat: replace `new` keyword with `this` constructor syntax and `ClassName.new()` calls across core library and docs Replace all uses of the `new` reserved word with explicit `this new()` constructor definitions and `ClassName.new()` instantiation calls in builtin/core.wren. Update all documentation files (classes.markdown, fiber.markdown, fn.markdown, sequence.markdown, error-handling.markdown, expressions.markdown, fibers.markdown, functions.markdown) to reflect the new constructor syntax, removing `new` keyword examples and replacing them with `ClassName.new()` patterns and `this new()` definitions.
