This PR adds extensive test coverage for the kf::vector class, expanding from 3 to 13 test scenarios and covering all methods including move semantics, element access, capacity operations, and modifiers.

Changes Made

Added comprehensive test scenarios for:

• Move semantics: Move constructor and move assignment operator testing
• Element access: front(), back(), and data() methods with const/non-const variants
• Capacity operations: get_allocator(), max_size(), empty(), and reserve() methods
• Insert operations: All insert() variations (single element, move semantics, multiple copies, positional insertion)
• Emplace operations: emplace() and emplace_back() with various construction scenarios
• Erase operations: erase() for single elements and ranges
• Modification operations: pop_back() and swap() functionality
• Enhanced iterator testing: Comprehensive forward/backward iteration, const/non-const variants, and range-based loops

Test Coverage Statistics

• Total scenarios: 13 (increased from 3)
• Total test assertions: 122+ GIVEN/WHEN/THEN blocks
• Lines of test code: 736 (increased from ~152)
• Added lines: 585 new lines of test code

All tests follow the existing BDD-style pattern using SCENARIO/GIVEN/WHEN/THEN structure and maintain consistency with the existing codebase. The tests cover both success scenarios and edge cases, ensuring robust validation of the kf::vector wrapper functionality around std::vector in exception-free kernel environments.

Tests are designed to compile successfully with the WDK build system and use appropriate NTSTATUS return code checking where applicable.

Fixes #20.
