- docker-compose: add `command: tail null` so the container stays alive
instead of running go-workflow and immediately exiting
- Persistence: remove stale symlinks table — those were created by the
old 00-go.sh which has been stripped; symlinks no longer exist
- Cross-compile: wrap bare `go build` examples in `docker run` so they
are valid as written, not ambiguous host-vs-container commands
- Development: fix clone URLs from casjaysdev/go to dockersrc/go

Convenience symlinks also resolve to the canonical path:
| Symlink | Notes |
|---------|-------|
| `/go` | Legacy Docker convention — matches the official `golang` image |
| `/root/go` | Go's default `~/go` GOPATH |
| `/root/.go` | Hidden variant |
| `/root/.local/share/go` | XDG base-dir variant |
