fix: Implement tap.todo(), fix tap.skip.test() to create test objects, and ensure tap.only.test() works correctly

- tap.todo.test() now creates proper test objects marked as todo
- tap.skip.test() creates test objects instead of just logging
- tap.only.test() properly filters to run only marked tests
- Added markAsSkipped() method for pre-test skip marking
- All test types now contribute to accurate test counts
- Updated documentation to reflect these fixes

+### tap.skip.test(), tap.todo(), and tap.only.test() (Fixed)
+
+Previously reported issues with these methods have been resolved:
+
+1. **tap.skip.test()** - Now properly creates test objects that are counted in test results
+   - Tests marked with `skip.test()` appear in the test count
+   - Shows as passed with skip directive in TAP output
+   - `markAsSkipped()` method added to handle pre-test skip marking
+
+2. **tap.todo.test()** - Fully implemented with test object creation
+   - Supports both `tap.todo.test('description')` and `tap.todo.test('description', testFunc)`
+   - Todo tests are counted and marked with todo directive
+   - Both regular and parallel todo tests supported
+
+3. **tap.only.test()** - Works correctly for focused testing
+   - When `.only` tests exist, only those tests run
+   - Other tests are not executed but still counted
+   - Both regular and parallel only tests supported
+
+These fixes ensure accurate test counts and proper TAP-compliant output for all test states.

-### Known Issues to Fix
-- **tap.todo()**: Method exists but has no implementation
-- **tap.skip.test()**: Doesn't create test objects, just logs (breaks test count)
+### Recently Fixed Issues ✅
+- **tap.todo()**: Now fully implemented with test object creation
+- **tap.skip.test()**: Now creates test objects and maintains accurate test count
+- **tap.only.test()**: Works correctly - when .only tests exist, only those run
+
+### Remaining Minor Issues
 - **Protocol Output**: Some protocol messages still appear in console output
-- **Only Tests**: `tap.only.test()` exists but `--only` mode not fully implemented
 
 ### Next Recommended Steps
-1. Add Watch Mode - high developer value
+1. Add Watch Mode (Phase 4) - high developer value for fast feedback
 2. Implement Custom Reporters - important for CI/CD integration  
-3. Fix known issues: tap.todo() and tap.skip.test() implementations
-4. Implement performance benchmarking API
+3. Implement performance benchmarking API
+4. Add better error messages with suggestions
