v0.2.0 - Single-Header Refactor

EWSS v0.2.0

Single-header refactor release. All code merged into a single include/ewss.hpp file (inspired by cpp-httplib).

Key Changes

• Single-header library: merged 7 hpp + 2 cpp files into one ewss.hpp (~1720 lines)
• No virtual dispatch: replaced virtual ProtocolHandler with StateOps function pointer table (zero overhead)
• No friend declarations: Connection internals exposed via accessor methods
• All comments in English
• CMake INTERFACE library: header-only, no compilation needed
• sockpp v2.0 API migration: updated to latest sockpp API

Testing

• 7 test suites, all passing
• Normal mode + -fno-exceptions mode verified
• CI: Linux-only (GCC + Clang, Debug + Release)

Dependencies

• sockpp (TCP socket wrapper, via FetchContent)
• Catch2 v3.5.2 (test only)
