Merge PR #62: Full OpenCode adapter integration

Merges paperclipai/paperclip#62 onto latest master (494448d).
Adds complete OpenCode provider with strict model selection,
dynamic model discovery, CLI/server/UI adapter registration.

Resolved conflicts with master's cursor adapter additions,
node v24 typing, and containerized opencode support (201d91b).
