Update javadocs and documentation with test coverage explanation

JavaDoc Updates:
- Add javadoc for RemoteClassSource timeout constants and fields
- Add javadoc for AuthConfig equals/hashCode/toString methods
- Document credential masking behavior in toString()

Documentation Updates:
- Add comprehensive "Test Coverage" section to README.md
- Explain why 46% coverage is intentional and appropriate
- Document what is tested vs what is not tested (and why)
- Break down coverage by package with rationale
- Update DOCUMENTATION_COMPLETE.md with current stats
- Reference Maven Wrapper addition in build status

Coverage Philosophy:
- Core functionality well-tested (53%, 83%, 82% in key packages)
- Example code intentionally not tested (0% - demo code)
- External integrations mocked for unit tests (40-66%)
- 463 tests provide focused, high-quality coverage

+### Test Coverage
+
+JClassLoader has **463 comprehensive unit tests** achieving **46% instruction coverage** across the codebase. While we strive for high test coverage, 100% coverage is not the goal for this project. Here's why:
+
+**What IS tested (well-covered):**
+- ✅ **Core functionality** (53% coverage): Class loading, delegation strategies, authentication
+- ✅ **Caching layer** (83% coverage): FileSystemCache, RedisClassSource
+- ✅ **Lifecycle system** (82% coverage): Event listeners, resource tracking
+- ✅ **Delegation strategies** (85% coverage): Parent-first, parent-last, custom
+- ✅ **Protocol handling** (100% coverage): Protocol registry and handlers
+- ✅ **Critical paths**: All main use cases and builder patterns extensively tested
+
+**What is NOT fully tested (and why):**
+- ❌ **Example code** (0% coverage in `org.flossware.jclassloader.example`): These are demo applications, not production code. Testing them would verify example syntax, not library functionality.
+- ❌ **Deep integration scenarios** (40% coverage in cloud/messaging): Full integration tests with real AWS S3, Azure Blob, Kafka, Redis, etc. would require running external infrastructure. We use mocks for unit tests and rely on real-world usage for integration validation.
+- ❌ **Error recovery edge cases**: Some network timeout paths, exotic authentication failures, and rare filesystem conditions are difficult to trigger reliably in unit tests.
+- ❌ **External system quirks**: Vendor-specific behaviors (Nexus API variations, cloud provider retry logic) are validated through manual testing and production usage.
+
+**Testing Philosophy:**
+- **Unit tests verify logic**, not infrastructure: We mock external services (HTTP clients, FTP connections, database connections) to test our code, not third-party libraries.
+- **Builder pattern coverage**: Every builder is tested for null validation, required fields, and correct object construction.
+- **Value object contracts**: All immutable objects (AuthConfig, MavenArtifact) have equals/hashCode/toString tests.
+- **Critical security paths**: Authentication, SSL/TLS validation, path traversal protection are thoroughly tested.
+
+**Coverage by package:**
+```
+org.flossware.jclassloader (core)        53%  ✅ Primary use cases
+org.flossware.jclassloader.cache         83%  ✅ High reliability needed
+org.flossware.jclassloader.lifecycle     82%  ✅ Critical for monitoring
+org.flossware.jclassloader.delegation    85%  ✅ Core isolation feature
+org.flossware.jclassloader.protocol     100%  ✅ Complete coverage
+org.flossware.jclassloader.cloud         40%  ⚠️  Mocked external APIs
+org.flossware.jclassloader.messaging     66%  ⚠️  Kafka/RabbitMQ mocked
+org.flossware.jclassloader.example        0%  ❌ Demo code, not tested
+```
+
+**Running coverage reports:**
+```bash
+mvn clean test jacoco:report
+# View report at: target/site/jacoco/index.html
+```
+
+The 46% coverage represents **high-quality, focused testing** of the library's core functionality. Additional coverage would primarily test external library behaviors or demo code, providing diminishing returns for the effort invested.
