This updates the version number to v2.4.5.

- Add root CMakeLists.txt with Conan integration
- Add conanfile.py and conanfile.txt for dependency management
- Add src/CMakeLists.txt as placeholder for source compilation
- Add BUILD.md with comprehensive build instructions
- Add .gitignore.cmake for CMake/Conan generated files

Dependencies managed by Conan:
- protobuf 3.21.12
- openssl 3.2.0
- zlib 1.3.1
- libcurl 8.5.0
- re2 20231101
- jemalloc 5.3.0
- gtest 1.14.0 (optional)

Features:
- Cross-platform build support (Linux, macOS, FreeBSD)
- Automatic dependency resolution and building
- ccache support for faster rebuilds
- Configurable build options (jemalloc, testing, static linking)
- Modern CMake best practices

- Fix make_optional template to return correct optional<decay_t<T>> type
- Update all make_optional() calls to be compatible with C++17
- Replace make_optional calls with direct optional<T> construction where needed
- Use custom make_optional implementation instead of std::make_optional

This fixes compilation errors where std::make_optional returns
optional<decay_t<T>> which was incompatible with the custom optional<T> class.

Note: QuickJS dependency is still missing and needs to be added separately.

- Document modern CMake-based build process
- Include Conan dependency management setup
- List build requirements and tools
- Provide quick start commands for users
- Link to detailed BUILD.md documentation

This update improves documentation for developers wanting to build
RethinkDB on various platforms using the new CMake infrastructure.

## Build System Improvements
- Add quickjs package dependency to CMakeLists.txt
- Correct CMake target linking (quickjs::quickjs)
- Update src/CMakeLists.txt with proper target configuration

## C++17 Compatibility Fixes
- Replace deprecated std::random_shuffle with std::shuffle
- Fix rapidjson Value string constructor calls (add length parameter)
- Fix re2::StringPiece to std::string conversions
- Replace non-existent as_string() with proper string construction

## Optional Type System Corrections
- Fix make_optional function definition in optional.hpp
- Remove redundant using rethinkdb::optional declarations
- Replace rethinkdb::optional with proper optional wrapper
- Fix boost::variant initialization with proper constructors
- Resolve optional<optional> type nesting issues

## Protocol Buffer and Variant Fixes
- Add explicit initialization for boost::variant change_t
- Use std::forward for proper rvalue reference handling
- Fix raft_core comparison logic with optional values

All changes ensure compatibility with C++17, modern Boost versions,
and cross-platform CMake builds on macOS, Linux, and other systems.

User-specific CMake presets should not be version controlled.
Each developer can generate presets locally as needed using:
  cmake --preset conan-release

- Document assignment_sentry.hpp with RAII guard details
- Document do_on_thread.hpp with thread execution API
- Document random.hpp with RNG utilities
- Document math.hpp with alignment and mathematical functions

- Update CMakeLists.txt project version
- Update conanfile.py version
- NOTES.md already contains v2.4.5 release information

- Document TLS macros with design rationale
- Document DEFINE_TLS_REF_ACCESSORS and DEFINE_TLS_ACCESSORS
- Document TLS(), TLS_with_get_ref(), and TLS_with_init() macros
- Document coroutine-based and standard C++17 implementations
- Document type trait compatibility macros

- Document stl_utils.hpp with STL container helpers
- Document memory_utils.hpp with aligned allocation functions
- Document time.hpp with time measurement utilities
- Document timestamps.hpp with state timestamp management
- Document repli_timestamp.hpp with replication timestamps

- Change logWRN(error_message.c_str()) to logWRN("%s", error_message.c_str())
- Prevents format-string injection vulnerability
- Eliminates Clang -Wformat-security warning

Adds a production-grade Go MCP server as a companion service to RethinkDB.
The C++ source is completely untouched.

Architecture:
- Transport layer: stdio (Claude Desktop) + HTTP+SSE (multi-client)
- Auth bridge: mirrors RethinkDB SCRAM-SHA-256 via gorethink driver
- Tool registry: 10 tools across 3 categories

Tools implemented:
  Introspection: list_databases, list_tables, describe_table
  CRUD:          query_reql, insert_document, update_document, delete_document
  Streaming:     subscribe_table_changes, subscribe_query_changes, unsubscribe

Streaming uses native RethinkDB changefeeds via gorethink cursors.
Each subscription runs in a dedicated goroutine with context cancellation.

Package dependency graph (no circular imports):
  auth → gorethink
  tools → auth, gorethink   (owns ToolDefinition/CallToolResult)
  protocol → tools, auth, transport
  main → all
