Bob Nystrom ca8f9faf18 feat: implement local variable declarations and symbol table in compiler and VM ...

Add support for local variable declarations with `var` keyword in the Wren compiler, including a symbol table for tracking locals within blocks. Introduce new bytecode instructions (CODE_POP, CODE_LOAD_LOCAL, CODE_STORE_LOCAL) and a call frame stack in the VM to manage local variable scopes during execution. Refactor the symbol table from a flat array to a proper SymbolTable struct with init/clear/add/ensure/find functions, and add a primitive method table for the num class with an `abs` method.

Description

Highly customized version of the wren programming language. It has all the modules that you would expect in a std library including http, websockets, sqlite3 and jinja-like templating engine. The idea is to make it suitable for web development.
