feat(plugin): Add opencode-conductor-plugin to ecosystem page

[derekbar90]

Built from Google Gemini Conductor principles.

Conductor is a specialized OpenCode plugin designed to enforce a rigorous, Context-Driven Development lifecycle. It transforms OpenCode from a reactive coding tool into a proactive project architect that follows a strict protocol to specify, plan, and implement software features and bug fixes.

The philosophy is simple: control your code by controlling your context. By treating project requirements and plans as managed artifacts, Conductor ensures every agent interaction is grounded in deep, persistent project awareness.
