Subject: [PATCH] Add forge-std compatible assertion aliases for easier
 integration

This PR adds assertion function aliases that match forge-std/Test.sol
naming conventions, resolving naming conflicts and enabling seamless
integration with existing Foundry codebases.

Problem:
When integrating crytic/properties with existing Foundry projects, many
assertion helpers collided with forge-std/Test.sol, making it difficult
to use both libraries together. Specific conflicts:
- assertWithMsg (crytic) vs assertTrue (forge-std)
- assertGte (crytic) vs assertGe (forge-std)
- assertLte (crytic) vs assertLe (forge-std)
- assertNeq (crytic) vs assertNotEq (forge-std)

Solution:
Added 8 new assertion function aliases in PropertiesHelper.sol that
delegate to existing implementations:
- assertTrue() - alias for assertWithMsg()
- assertFalse() - new function for asserting false conditions
- assertNotEq() - alias for assertNeq() (uint256 and int256)
- assertGe() - alias for assertGte() (uint256 and int256)
- assertLe() - alias for assertLte() (uint256 and int256)

Benefits:
- Users can now inherit from both PropertiesAsserts and forge-std Test
  without naming conflicts
- Both naming conventions work side-by-side
- 100% backward compatible - existing code continues to work
- No breaking changes to existing properties
- Easier onboarding for Foundry developers

Example usage:
```solidity
contract MyTest is MyToken, CryticERC20BasicProperties, Test {
    function test_example() public {
        // Both styles work!
        assertTrue(balance > 0, "Has balance");  // forge-std style
        assertWithMsg(balance > 0, "Has balance"); // crytic style

        assertGe(balance, 100, "At least 100"); // forge-std style
        assertGte(balance, 100, "At least 100"); // crytic style
    }
}
```

This change makes crytic/properties fully compatible with Foundry's
standard testing patterns, lowering the barrier to adoption.
