* ci: optimize build workflows - use go version from go.mod instead of hardcoding - group platforms by OS for parallel builds - remove legacy try-build targets * fix: checkout before setup-go in all workflows setup-go needs go.mod to be present, so checkout must happen first * chore: remove deprecated // +build syntax go 1.17+ uses //go:build, the old syntax is no longer needed * simplify: remove nofuse tag from CI workflows - workflows now rely on platform build constraints - keep make nofuse target for manual builds - remove unused appveyor.yml * ci: remove legacy travis variable and fix gateway-conformance - remove TRAVIS env variable from 4 workflows - fix gateway-conformance checkout path to match working-directory - replace deprecated cache-go-action with built-in setup-go caching
