fix(opencode-go): remove dead mcps property from librarian mapping

createAgentConfig uses DEFAULT_AGENT_MCPS, so the hardcoded mcps in
MODEL_MAPPINGS was dead code. Add orchestartor variants to kimi, copilot,
and zai-plan presets for consistency. Fix doc claim about per-agent skills/mcps.

 ## Skill Reference
 
-This preset defines no per-agent `skills` or `mcps`. All agents use whatever skills are globally installed (the `*` wildcard).
+This preset defines per-agent `skills` and `mcps` via `generateLiteConfig`. The generated config includes `skills: ["*"]` for Orchestrator and agent-specific MCP lists (e.g., Librarian gets `websearch`, `context7`, `gh_grep`).
