Enables clean builds under GOOS=windows CGO_ENABLED=0 and under
CGO_ENABLED=0 on Linux. The three tools that can't be built in those
configurations now substitute a stub that prints a clear message
and exits 1, so go build ./... succeeds across all target platforms.
- tools/sniff: tagged !windows && cgo (needs libpcap via cgo).
Stub (main_stub.go) covers windows || !cgo.
- tools/split: same tags as sniff (also pcap).
- tools/sniffer: tagged !windows (uses Unix raw sockets directly via
syscall, not cgo). Stub (main_windows.go) covers Windows.
Verified:
- go build ./... clean (default, cgo=1 Linux)
- CGO_ENABLED=0 go build ./... clean (portable Linux)
- GOOS=windows CGO_ENABLED=0 go build ./... clean (Windows)
- go vet clean across all three configurations
- All 13 pkg/transport tests pass under CGO_ENABLED=0, confirming
direct_portable.go's directDial path is correct.
