Rename the project to shadowsocks-c while retaining ss-* commands, the embedding ABI, and legacy library/package lookup compatibility.
Replace libev with bundled libuv for IOCP/kqueue event backends, expand asynchronous runtime DNS coverage, and add actionlint/Ruff with strict clang-tidy failure handling. Validate native platforms, static builds, packaging, interoperability, sanitizers, and canonical/legacy consumers.
All 22 hosted checks pass at reviewed head a8493250eb.
