Aleksi Salmela 5268170c89 fix: guard against local variable array overflow from for-loop hidden variables

Add a bounds check in `forStatement` to ensure there is space for the two hidden local variables (sequence slot and iterator) before calling `addLocal`. Without this check, deeply nested for-loops could overflow the `locals` array, causing a buffer overrun. The fix emits a clear compiler error when `numLocals + 2` exceeds `MAX_LOCALS`, and includes a regression test with 85 nested for-loops that previously triggered the overflow.

README.md

This contains the automated validation suite for the VM and built-in libraries.

benchmark/ - Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself.
core/ - Tests for the built in core library, mainly methods on the core classes. If a bug is in wren_core.c or wren_value.c, it will most likely break one of these tests.
language/ - Tests of the language itself, its grammar and runtime semantics. If a bug is in wren_compiler.c or wren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes.
limit/ - Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
