Integrate OCM into existing OC setups by default #131

This is some UX Feedback based on my user journey:

README says OpenCode Manager is a web interface for OpenCode, but from my user journey perspective it feels more like a fork of OpenCode right now:

I was using OpenCode before and looking for a way to access it from my phone. But after setting up OpenCode Manager, none of the OpenCode settings from my host were applied in the webui. Models, MCPs, Repos. It felt like a fresh install.
I think many users don't wanna take this journey if they see they need to set up everything from scratch again.

I tired to integrate OCM into my existing OC setup by:

• bind mounting my repos Data-loss risk: orphan cleanup deletes bind-mounted repos #128
• bind mounting my auth.json config dir Model selector shows no models when provider payload omits cost.cache #129
• bind mounting my mcp config dir Repo MCP dialog ignores directory-level MCP status when default config has no mcp #130

My docker-compose.yml now looks like this:

volumes:
  - opencode-workspace:/workspace
  - /home/sam/workspace:/workspace/repos
  - opencode-data:/app/data
  - /home/sam/.local/share/opencode:/workspace/.opencode/state/opencode
  - /home/sam/.config/opencode:/workspace/.config/opencode

But I think my auth is not working yet because of #129

Expected

Quick Start Guide and docker-compose.yml should suggest bind mounts to integrate OCM seamless into existing OC setups.
