🔄 ENHANCED - OpenCode Attach Integration (from SPEC-005)

This issue now includes the implementation of SPEC-005 (CLI-to-Server Attach):

New Implementation Approach:

# agentworkspace attach my-project
# 1. Get pod IP from K8s API
# 2. Call: opencode attach ws://<pod-ip>:9090
# 3. Handle reconnection/auth

# For BYOC fallback:
# kubectl port-forward <pod> 9090:9090
# opencode attach ws://localhost:9090

Rationale:

• Using OpenCode native opencode attach instead of kubeconfig
• No kubectl dependency for standard attach workflow
• See PDR-045 (revised) for details

Dependencies

• SPEC-007: Base Image Layers (GitLab: tikalk/engineering/agentic-sdlc/adlc-agent-workspaces#1)
• SPEC-008: Dockerfile Overlay System (GitLab: tikalk/engineering/agentic-sdlc/adlc-agent-workspaces#2)
• SPEC-005: CLI-to-Server Attach - CLOSED, merged into this issue
