🔧 Fixed shm_unlink failures with proper '/' prefix handling

Comprehensive Unit Test Suite (#159)

📦 Complete test refactoring with comprehensive coverage
✅ New tests for: buffer, shm, mutex, semaphore, condition, locks, route, channel
🎯 Improved test quality with proper edge case handling
📝 Better test documentation and semantics

Windows Shared Memory Reference Counting

🔢 Implemented full reference counting for Windows shared memory
✅ Now matches POSIX behavior
🔧 Fixed all reference counting tests on Windows

🔧 Bug Fixes

Critical Fixes

🐛 Fixed double-free bugs in shared memory tests
🐛 Fixed segfault in EOWNERDEAD handling
🐛 Fixed FreeBSD segfault by unlocking mutex before destruction
🐛 Fixed mutex unlock timing to avoid interfering with other references
🐛 Fixed ODR violations in get_wait_time inline functions
🐛 Fixed namespace conflicts with predefined 'linux' macro

Buffer Improvements

🔧 Removed const from char constructor to prevent undefined behavior
🔧 Removed redundant const qualifier in array constructor
🔧 Renamed 'additional' parameter to 'mem_to_free' for clarity

Test Fixes

🔧 Fixed receiver loop count in MultipleSendersReceivers test
🔧 Corrected test logic in multiple test cases
🔧 Fixed id_t ambiguity in test_shm.cpp
🔧 Replaced C++17 structured bindings with C++14 compatible code
🔧 Changed test indentation from 4 spaces to 2 spaces

Platform Compatibility

🔧 Fixed permission issues under Linux (#139)
🔧 Fixed MinGW compatibility - use lowercase windows.h (#157)
🔧 Improved POSIX shared memory error logging

✨ Enhancements

Cleanup Interfaces

🧹 Added cleanup interfaces for shared memory handles
🧹 Added cleanup interfaces for queue

Connection Management (#145, #148)

🔌 Fixed connection slot full判断错误 (#145)
🔌 Fixed issues #107 and #123 - receiver checks connection when pop fails
🔌 In non-broadcast mode, connection tags are only used for counting

Build System

📦 Added PACKAGE_VERSION
📦 Added cpp-ipc-targets
📦 Updated CMakeLists.txt for new test structure

Code Quality

🎨 Improved name handling in shm_posix.cpp to match semaphore pattern
