Restructure Compiler to use dynamic bytecode and constant buffers instead of
relying on ObjFn's fixed-size arrays. Move ObjFn creation to the end of
compilation, add wrenListAdd/Insert/RemoveAt helpers to wren_value, relocate
list capacity macros and ensureListCapacity into wren_value.c, and store a
Compiler pointer in WrenVM for GC safety during compilation.
Remove the ResolvedName enum and its typedef, replacing the resolved parameter with a Code* loadInstruction pointer that directly returns the appropriate load instruction (CODE_LOAD_LOCAL, CODE_LOAD_UPVALUE, or CODE_LOAD_GLOBAL). This eliminates the intermediate enum and the TODO comment about ditching it, simplifying the variable resolution logic in the compiler.
Migrate all boolean-typed parameters, return values, struct fields, and local variables from `int` (with 0/1 convention) to C99 `bool` (`true`/`false`). Update corresponding comments, macro definitions, and documentation strings to use `true`/`false` terminology instead of "non-zero"/"zero". Add `#include <stdbool.h>` to `src/main.c`, `src/wren_compiler.c`, and `src/wren_value.h`. Remove the stale TODO comment in `src/wren_common.h` that originally proposed this change.
Remove "(bob)" author prefix from all TODO comments in benchmark/method_call.wren, include/wren.h, src/main.c, src/wren_common.h, src/wren_compiler.c, src/wren_core.c, src/wren_value.c, src/wren_value.h, and src/wren_vm.c. Update the TODO_PATTERN regex in metrics script to match the new format without author parentheses. Also refactor test file counting in metrics to use os.walk with fnmatch for recursive directory traversal instead of glob.iglob.
Convert all conditional compilation guards from bare `#ifdef NAN_TAGGING` to `#if WREN_NAN_TAGGING` across wren_common.h, wren_value.c, wren_value.h, and wren_vm.c. Introduce new `#ifndef`-based defaults for WREN_NAN_TAGGING, WREN_COMPUTED_GOTO, WREN_DEBUG_GC_STRESS, and WREN_TRACE_MEMORY in wren_common.h, replacing the old TODO comments and commented-out debug flags. Update preprocessor indentation style for consistency.
When a class is defined, its superclass is not known until runtime since class definitions are imperative statements. This adds a new wrenBindMethod function that walks the bytecode of a method after it is bound to a class, adjusting LOAD_FIELD/STORE_FIELD indices to account for inherited fields and patching superclass dispatch targets. The newClass function now correctly accumulates numFields from the superclass chain, and the VM calls wrenBindMethod when binding methods to a class. Includes new test files for inherited field access and the is operator.
