refactor(tools): bin/{subject}/{method} layout; Go serve+watch modules

Move serve/ (module) -> bin/server, tools/ -> bin/tools, replace bin/kb-watch bash with bin/watch Go package; self-executing Go shebangs bin/serve.go and bin/kb/watch.go; Docker + CI + git/import + docs repointed. Multi-stage image builds static serve+watch binaries (no Go runtime in container).
