Changes:
- Removed --admin-password argument (no longer needed)
- Password auto-generated: folder_name.lower().replace(' ', '')
- Each website has unique password
- No need to ask user for password
Examples:
- moreminimore → password: moreminimore
- My Website → password: mywebsite
- deal-plustech → password: deal-plustech
Benefits:
- Simple (same as folder name)
- Secure (different per project)
- No password management needed
- Not stored in git (in .env)
- Changed from Dockerfile to nixpacks (no Dockerfile needed)
- Astro projects automatically detected and built by nixpacks
- Simpler deployment, no Docker configuration required
- Load credentials from ~/.config/opencode/.env automatically
- No need to configure .env in each skill directory
- Fixes issue where new skills couldn't find credentials
