Add IGNORE_TEST and IGNORE_TEST_F macros 🚀

This feature allows developers to temporarily disable specific tests without removing them from the codebase. This is particularly useful when:

Working on experimental features
Dealing with temporarily broken tests
Handling environment-dependent tests
Managing long-running tests during development

New Macros ✨

Two new macros have been added:

IGNORE_TEST() - for regular test cases
IGNORE_TEST_F() - for fixture-based tests

Usage Example 💡

#include <tau/tau.h>

// Regular test case that will be executed
TEST(MathSuite, Addition) {
    int result = 2 + 2;
    CHECK_EQ(result, 4);
}

// This test will be ignored but remains in the codebase
IGNORE_TEST(MathSuite, ComplexCalculation) {
    int result = perform_complex_calculation();
    CHECK_EQ(result, 42);
}

// Setup for fixture
TEST_F_SETUP(DatabaseFixture) {
    tau->db = database_connect();
}

// Teardown for fixture
TEST_F_TEARDOWN(DatabaseFixture) {
    database_disconnect(tau->db);
}

// This fixture test will be ignored but setup/teardown are preserved
IGNORE_TEST_F(DatabaseFixture, SlowQuery) {
    bool query_result = database_execute_heavy_query(tau->db);
    CHECK_TRUE(query_result);
}

// This fixture test will run normally
TEST_F(DatabaseFixture, QuickQuery) {
    bool query_result = database_execute_simple_query(tau->db);
    CHECK_TRUE(query_result);
}

Output Example 🖥️

[==========] Running 4 test suites.
[ RUN      ] MathSuite.Addition
[       OK ] MathSuite.Addition (0.001s)
[ IGNORED  ] MathSuite.ComplexCalculation
[ RUN      ] DatabaseFixture.QuickQuery
[       OK ] DatabaseFixture.QuickQuery (0.003s)
[ IGNORED  ] DatabaseFixture.SlowQuery
[==========] 2 test suites ran
[  PASSED  ] 2 suites

Summary:
    Total test suites:          4
    Total suites run:           2
    Total warnings generated:   0
    Total suites skipped:       2
    Total suites failed:        0

Implementation Details 🔧

Added ignored flag to test suite structure
Extended test registration to support ignored state
Modified test runner to handle ignored tests
Maintained existing color coding (yellow for ignored tests)
Updated test statistics to properly count ignored tests

Backwards Compatibility ⚡

This change is fully backwards compatible:

Existing tests continue to work as before
No changes required to existing test code
No changes to command-line interface

Testing 🧪

The implementation has been tested with:

Regular test cases
Fixture-based tests
Mixed ignored and regular tests
Various output formats (colored, non-colored)
