Add GitHub Actions CI for Linux and Windows

* deps(cmake): require GTK>=3.24/GLib>=2.76, GStreamer 1.x only; prefer Ayatana tray; libcurl via pkg-config; default to OpenSSL; keep GnuTLS/libgcrypt optional

* cmake: guard pkg-config usage by availability

This PR resolves build failures on Windows and Linux and modernizes the CMake build system.

Changes include:
- Fixed Windows compilation error (snprintf macro redefinition)
- Fixed Linux segmentation fault in tests (pointer arithmetic)
- Refactored CMakeLists.txt to build proper targets
- Fixed memory leaks and linking issues in tests
- Added optional toggle for Mega plugin with robust detection
- Updated vcpkg baseline and dependencies

This adds src/main.c to CMakeLists.txt and makes it a valid entry point, ensuring uget.exe is built.
