Add assert cheatcodes

[tuturu-tech]

Add assert* cheatcodes: assertTrue, assertFalse, assertEq (6 type variants), assertNotEq (6 type variants), and assertLt/Le/Gt/Ge (8 comparison operators). Tested each, most assertions return Panic(0x01) on failure (assertFalse and assertTrue don't, I wasn't able to figure out why)

Testing:

• TestAssertCheatCodesPass: Verifies passing assertions work correctly
• TestAssertCheatCodesFail: Verifies failing assertions are detected and return panic code 0x01

TODO:

• [ ] Debug assertTrue and assertFalse
