Remove packages now in their own repos:
- go-crypt: crypt, auth, trust
- go-ai: ml, mlx, agentic, ai, rag, mcp
- go-devops: build, release, sdk, deploy, ansible, devops, container, infra, devkit
- go-scm: forge, gitea, git, agentci, jobrunner, collect
- go-netops: unifi
Make crypt service registration optional in CLI framework
(consumers wire it in via Options.Services). Add go-crypt as
test dependency for workspace package.
core/go is now a pure foundation library (~24K LOC, 17 packages).
