Modernize build/CI, support SourceMod 1.13, deprecate ForceHeartbeat
Rework the build and CI: swap to SourceMod's safetyhook-based CDetour and drop the vendored CDetour/asm sources, the old Makefile, Travis config, and buildbot perl scripts. Add GitHub Actions building and releasing x86 and x86_64 against SM 1.12 and 1.13, plus dependabot. Split the Windows and Linux packages and tidy naming. Gate IPluginManager::FindPluginByContext on the extension API version so the extension builds against both SM 1.12 (API 8) and 1.13 (API 9), and shim DETOUR_CREATE_STATIC_FIXED over the address overload safetyhook exposes. Deprecate SteamWorks_ForceHeartbeat: newer Steamworks SDKs removed ISteamGameServer::ForceHeartbeat, so make the native a no-op and mark it deprecated in the include.
