feat: update AI automation agents, add reviewer agent, fix leaks, enhance CI
Agents: - cmake-expert: fix stale CMake version (4.1 -> 3.22), add OpenSSL/xxHash deps - integrator: fix stale test.py references to tests/integration/, update CI docs - test-writer: update integration test patterns for modular test structure - reviewer: new comprehensive PR reviewer (code, build, CI, docs, quality) Bug fixes: - delta.c: set instructions[i].type = DELTA_INSTR_LITERAL in deserialize - scanner.c: free ArrayList when directory_scanner_next returns NULL CI: - Add sanitizer job (ASan + UBSan) with LSAN suppressions for pre-existing leaks - Add clang-tidy job with proper warning/error detection - Remove || true masking (fixes now make sanitizer useful) Cleanup: - gitignore build-asan/ - .lsan-suppressions.txt for known CLI config leaks

## When Adding Sanitizer Support to CMakeLists.txt
|
||||
## Sanitizer Integration
|
||||
|
||||
Use CMake options for cleaner integration:
|
||||
The project uses a single `SANITIZER` cache variable in `CMakeLists.txt`:
|
||||
```cmake
|
||||
option(ENABLE_ASAN "Enable AddressSanitizer" OFF)
|
||||
option(ENABLE_TSAN "Enable ThreadSanitizer" OFF)
|
||||
option(ENABLE_UBSAN "Enable UndefinedBehaviorSanitizer" OFF)
|
||||
|
||||
if(ENABLE_ASAN)
|
||||
add_compile_options(-fsanitize=address -fno-omit-frame-pointer)
|
||||
add_link_options(-fsanitize=address)
|
||||
endif()
|
||||
|
||||
if(ENABLE_TSAN)
|
||||
add_compile_options(-fsanitize=thread)
|
||||
add_link_options(-fsanitize=thread)
|
||||
endif()
|
||||
|
||||
if(ENABLE_UBSAN)
|
||||
add_compile_options(-fsanitize=undefined)
|
||||
add_link_options(-fsanitize=undefined)
|
||||
endif()
|
||||
set(SANITIZER "none" CACHE STRING "Sanitizer to enable (address, thread, none)")
|
||||
set_property(CACHE SANITIZER PROPERTY STRINGS address thread none)
|
||||
```
|
||||
Supported values: `address`, `thread`, `none`. Unknown values trigger `FATAL_ERROR`.
|
||||
|
||||
Then build with:
|
||||
Build with:
|
||||
```bash
|
||||
cmake -B build -S . -DENABLE_ASAN=ON
|
||||
cmake -B build -S . -DSANITIZER=address
|
||||
cmake --build build -j$(nproc)
|
||||
```
|
||||
|
||||
To add support for a new sanitizer (e.g., UBSan), add an `elseif(SANITIZER STREQUAL "undefined")` block following the existing `address`/`thread` pattern.
