Implementation

Implement exception handling macros using setjmp/longjmp to simulate try/catch/throw.

Requirements:

Define TRY, CATCH, THROW, FINALLY macros
Handle nested function calls with error propagation
Demonstrate proper resource cleanup
Show error handling example with multiple exception types

Why This Matters

setjmp/longjmp is C's exception mechanism and it is load-bearing in real systems: CPython's signal handling, Lua's error handling (lua_error), and libpng's error recovery are all built on it. Implementing with it teaches the register-snapshot model that also underlies coroutines, green threads, and why C++ exceptions need unwind tables.
