feat: update AI automation agents, add reviewer agent, enhance CI

- Update cmake-expert agent: fix CMake version (3.22 not 4.1), add OpenSSL/xxHash deps
- Fix integrator agent: update stale test.py references to tests/integration/
- Fix test-writer agent: update integration test patterns for modular test structure
- Add reviewer agent: comprehensive PR review covering code, build, CI, docs, quality
- Enhance CI: add sanitizer job (ASan+UBSan) and clang-tidy static analysis job

 ### Gitea Workflow Structure (`.gitea/workflows/ci.yaml`)
 The project uses Gitea Actions. Key jobs:
-1. **Build** — compile on push/PR
-2. **Unit tests** — run `./build/tests`
-3. **Integration tests** — run `python3 test.py` (light mode)
-4. **Sanitizer builds** — ASan, TSan variants
+1. **build-and-test** — compile, unit tests, integration tests on push/PR
+2. **sanitizer** — ASan + UBSan build and test (separate job)
+3. **clang-tidy** — static analysis on C source files
