Closes #5

Summary

This pull request implements comprehensive CMake modernization for C/C++ Pro, introducing a hybrid intelligence architecture that combines instant zero-binary static parsing with full ingestion of modern CMake FileAPI, CMake Presets, target debugging, CTest runner, and single-file compilation.

Key Capabilities

1. Hybrid CMake FileAPI Ingestion (codemodel-v2)

• Ingests .cmake/api/v1/reply/ artifacts (codemodel-v2, cache-v2, toolchains-v1) when available in configured build directories.
• Extracts 100% ground-truth compiler flags, include paths, defines, sysroots, and target definitions without spawning external processes.
• Gracefully falls back to C/C++ Pro's zero-binary static AST parser when a project is unconfigured or CMake has not yet run.
• Watches .cmake/api/v1/reply/*.json for seamless auto-reload when external builds run.

2. CMake Presets Support (CMakePresets.json & CMakeUserPresets.json)

• Native support for CMake Presets schema versions 1 through 9+ (CMake 3.19 through 3.31+).
• Supports configurePresets, buildPresets, and testPresets with developer overrides in CMakeUserPresets.json.
• Evaluates standard CMake macros (${sourceDir}, ${presetName}, ${generator}, ${hostSystemName}, ${pathListSep}, ${env:VAR}).
• Commands: c-cpp-pro.cmake.selectConfigurePreset and c-cpp-pro.cmake.selectBuildPreset.

3. Target-Aware Launch & Debug Engine

• Discovers executable targets from FileAPI artifacts and static declarations.
• Active target selector widget on the status bar (c-cpp-pro.cmake.selectLaunchTarget).
• Direct DAP debugging (c-cpp-pro.cmake.debugTarget) via lldb-dap, cppvsdbg, or gdb without manual launch.json authoring.
• Direct execution in integrated terminal (c-cpp-pro.cmake.launchTarget) using native TerminalOptions.cwd.

4. CTest Integration in Test Explorer

• Discovers CTest test suites via ctest --show-only=json-v1 or parsing CTestTestfile.cmake.
• Integrates CTest tests directly into VS Code's native Test Explorer (vscode.tests).
• Supports both Run and Debug test execution profiles.

5. Single-File Quick Compilation

• Command and editor context menu action: c-cpp-pro.cmake.compileActiveFile.
• Compiles the active source file in syntax-only / check mode (-fsyntax-only / /Zs) to verify syntax and template instantiations in seconds without whole-project linkage.

6. Multi-Compiler Problem Matcher

• Line-by-line regex problem matcher for GCC, Clang, and MSVC compiler diagnostics.
• Supports Windows drive letters (C:\...), POSIX paths, coordinates, and diagnostic error codes (e.g. C2065).
• Streams diagnostics directly into vscode.DiagnosticCollection('c-cpp-pro-build').

7. AST-Assisted "Add to CMake Target" Refactoring

• CodeAction provider (CMakeCodeActionProvider) offering quick refactorings for untracked workspace C/C++ files.
• Modifies CMakeLists.txt inserting files into target_sources() or target declarations while preserving indentation.

8. Documentation

• Updated wiki/Static-CMake-Integration.md covering the hybrid FileAPI architecture, presets, debugging, and command reference.
