fix(providers): align opencode-go preset variants

Variants not exposed by a model are silently dropped, leaving the agent
without the intended reasoning strength. This aligns the preset with
opencode's provider/transform.ts variants() map.

Also simplify the opencode-go JSON examples in the READMEs to match
docs/opencode-go-preset.md (omit skills/mcps, which the installer
auto-injects from DEFAULT_AGENT_MCPS and CUSTOM_SKILLS)
