Move agentclaudecode repo to nimsforest GitHub org

agentclaudecode currently lives at github.com/cederikdotcom/agentclaudecode but functionally belongs to the NimsForest ecosystem (consumes agent.work.ai.claudecode.> on the forest's NATS, deploys to org Land servers, follows runbook/testbook conventions).

We just moved agentcodex to github.com/nimsforest/agentcodex for this reason (see issue #96 history). agentclaudecode is the remaining inconsistency.

Steps to fix (mirror what we did for agentcodex):
1. gh api -X POST /repos/cederikdotcom/agentclaudecode/transfer -f new_owner=nimsforest
2. git -C /home/claude-user/agentclaudecode remote set-url origin git@github.com:nimsforest/agentclaudecode.git
3. Update go.mod module path: github.com/cederikdotcom/agentclaudecode -> github.com/nimsforest/agentclaudecode
4. Update internal import paths in cmd/agentclaudecode/main.go (localharness + runner)
5. go build ./... && go vet ./... to verify
6. Commit + push to nimsforest/agentclaudecode main
7. Optionally tag a new patch release so the next CI build publishes under the new org name
