Bob Nystrom 86015f4e48 feat: add numParams tracking and arity-checked fn.call variants for extra/missing args
Add `numParams` field to `ObjFn` and `Compiler` structs to track expected parameter count. Refactor `parameterList` to return count and store it in compiler. Modify `endCompiler` to pass `numParams` to `wrenNewFunction`. Replace single `fn_call` native with 17 arity-specific `fn_call0` through `fn_call16` natives that validate argument count against `fn->numParams` via `callFunction` helper, returning error on missing args. Remove stale TODO comment in VM interpreter. Add test files `call_extra_arguments.wren` and `call_missing_arguments.wren`.

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.
